renderings is a dark art. Full of nonintuitive jargon and seemingly random UI choices, you can spend days getting nowhere. To make matters worse, this project calls for photo-real renderings, but we won&#8217;t be diving into full material modeling in a meaningful way until the next project.<\/p>\n\n\n\n<p>Thus, we will cheat. Below you will find some useful settings and tips to get you through your first real material rendering exercise with your sanity intact. Never mind that much of this is meaningless to you right now \u2014 take it on faith that these recommended settings will work. The kinds of materials this limits us to are generally materials with a uniform appearance: glass, plastic, metals, rubber, painted surfaces, certain stone types, terra-cotta pottery, and the like. But we can develop some surface sophistication within these choices: brushed or sandblasted, polished or matte, mirrored or painted. We avoid wood, fabric, and other non-uniform materials, but there&#8217;s still a lot to choose from to achieve photo-real results.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image is-style-default\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" data-attachment-id=\"1653\" data-permalink=\"https:\/\/williamcromar.com\/newmediawiki\/elements\/render\/\" data-orig-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render.jpg\" data-orig-size=\"1769,1769\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"render\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-1024x1024.jpg\" src=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-1024x1024.jpg\" alt=\"\" class=\"wp-image-1653\" srcset=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-1024x1024.jpg 1024w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-300x300.jpg 300w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-150x150.jpg 150w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-768x768.jpg 768w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-1536x1536.jpg 1536w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render-100x100.jpg 100w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/render.jpg 1769w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><em>A typical material sample model, created in a famous but now sadly abandoned rendering engined called&nbsp;<strong>mental ray<\/strong>.<\/em><\/figcaption><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>The renderer we will use is the standard <strong>Arnold<\/strong> renderer that comes pre-installed as a plug-in with Maya. But be aware: many exist. <strong>RenderMan<\/strong>, <strong>POVRay<\/strong>, and the now deceased <strong>mental ray<\/strong> are but a few examples. Each of these are plug-ins, which can be purchased and added to modeling software. A rendering engine often comes with its own library of shaders and lights. Since we&#8217;re using Arnold, it&#8217;s generally best to stay within Arnold&#8217;s options.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Material_issues\"><\/span>Material issues<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Material modeling and rendering is not a one-button affair. In other words, setting up material is more than just a material issue. There are several sets of parameters to develop, in this workflow order:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Loading the plug-in (if not present)<\/strong><\/li>\n\n\n\n<li><strong>Lighting<\/strong><\/li>\n\n\n\n<li><strong>Render Settings<\/strong><\/li>\n\n\n\n<li><strong>Materials<\/strong><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Loading_the_plug-in\"><\/span>Loading the plug-in<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>From time to time the rendering plug-in does not automatically load. If you do not see evidence that Arnold has loaded up, in any menu set go to <strong>Windows&gt;Settings\/Preferences&gt;Plug-in Manager<\/strong>. Scroll down (it&#8217;s near the bottom) and you should see a heading <strong>Applications\/solidangle\/mtoa\/20XX\/plug-ins<\/strong> (with XX being the year of issue). Under this heading should be a checked box named <strong>Loaded<\/strong>. If it is not checked, check both <strong>Loaded<\/strong> and <strong>Auto load<\/strong> boxes and hit <strong>Refresh<\/strong>, then <strong>Close<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Lighting\"><\/span>Lighting<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If you think about it, we don&#8217;t see material. We see the light bouncing around, onto, through, and off of material objects, so it only makes sense to develop the lights first. Setting up lights also includes creating shadows \u2014 surprisingly, lights often don&#8217;t automatically make them.<\/p>\n\n\n\n<p>In our sample file, we use a simple light: the Arnold Area Light. Be aware that Arnold has special settings in its own tab here (which, if not present, means you need to load the plug-in as per above). We don&#8217;t use the typical Raytrace shadows other rendering engines use because Arnold carries its own internally.&nbsp;<em>For the sake of brevity, any data in the Attributes that we don&#8217;t change, we won&#8217;t include in this or any other list of settings<\/em>. The settings to change in the Attribute Editor are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Intensity: 100<\/li>\n\n\n\n<li>Light shape: quad (but wait, it&#8217;s round? The next setting is the trick)<\/li>\n\n\n\n<li>Roundness: 1<\/li>\n\n\n\n<li>Soft edge: 1<\/li>\n\n\n\n<li>Samples: 4<\/li>\n\n\n\n<li>Check on Normalize, Cast Shadows, Cast Volumetric Shadows<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_do_these_numbers_work_here\"><\/span><strong><em>Why do these numbers work here?<\/em><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>All of these values work together to create a light with <strong>soft shadow edges<\/strong>, providing greater realism, though at the cost of increased render time:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>Intensity<\/strong> is quite bright. Arnold is a notoriously dark renderer.&nbsp;<\/li>\n\n\n\n<li>Arnold likes to use <strong>Exposure<\/strong> to set the strength of the light in a render, and here 1 works. Instead of tweaking Intensity, you can tweak the exposure value to get brighter renders. I tend to work a render a bit dark (because you get more information into the scene that way) and then tweak it in Photoshop.<\/li>\n\n\n\n<li><strong>Roundness<\/strong>, <strong>Soft edge<\/strong>, and <strong>Samples<\/strong> work together to create a smooth, non-sharp edge to shadows overall. The higher the Sample value, the smoother, and the larger the Roundness, the less sharp.<\/li>\n\n\n\n<li><strong>All the shadow settings<\/strong> checked create&nbsp;a dark shadow but not pure black like on the Moon. Shadows on Earth carry a bit of light bounced around by the atmosphere and hence are less dense.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>Keep in mind the more lights in a scene, the more render time this creates. However, a scene more natural than our sample file will typically have lights from many sources. Look around your room and identify how many sources of light there are. For simplicity, we typically use at least one major light and one minor light (photographers often call the minor light a <strong>fill light<\/strong>, as it fills areas the primary light does not). We try to avoid any unnecessary light load on the renderer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Render_Settings\"><\/span>Render Settings<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>After lighting, without proper render settings, you&#8217;ll still see nothing. In the Rendering menu set, go to <strong>Render&gt;Render Settings&#8230;<\/strong> or hit the <strong>Render Settings<\/strong> icon \u2014 a clapboard with a gear overlay \u2014 on the <strong>Status Bar<\/strong>. We select <strong>Render Using: Arnold Renderer<\/strong> and go to the <strong>Common<\/strong> and <strong>Arnold Renderer<\/strong> tabs to set the variables at right.

Noise is a term that refers to pixel randomization perceived to be too random and textured. Arnold is capable of creating quite smooth and appropriately uniform color gradations within a rendering, but it is notoriously noisy, and it&#8217;s difficult to discern what the source of the noise is. More on this topic below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Materials\"><\/span>Materials<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>For this project we keep it simple: avoid cloth, wood, marble, or any kind of material exhibiting texture or internal color changes. Using uniform materials still permits a great variety of choices, as we can see below.<\/p>\n\n\n\n<p>Simple materials are based on common Maya materials: <strong>Anisotropic<\/strong>, <strong>Blinn<\/strong>, <strong>Lambert<\/strong>, <strong>Phong,<\/strong> and PhongE. These do an adequate job of suggesting material without costing a lot in terms of rendering time. The biggest liability with Maya materials is found in metallic and glass materials, where refraction is limited or non-existent. In the illustration below, the back row is rendered using Maya standard materials.<\/p>\n\n\n\n<p>If you have the processor capability for more realistic reflections and refractions, try the <strong>aiStandard<\/strong> material under the <strong>Arnold&gt;Shader<\/strong> options in the <strong>Assign New Material<\/strong> dialog box. The <strong>aiStandard<\/strong> is an accurate material that can model almost any kind of surface by just selecting and tweaking a common set of variables. Unlike Maya standard materials, regardless of surface, the parameter categories and names remain identical, making for a refreshingly logical user interface. In the illustration, the front row duplicates the back row in <strong>aiStandard<\/strong>. The biggest problem&nbsp;is that it is a processor hog and takes a long time to render.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Demo_file_data\"><\/span>Demo file data<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Open the demo file linked above, named&nbsp;<strong>material_samples_ai_v_maya.mb<\/strong>, and make the layer named <strong>standards<\/strong> visible.&nbsp;Below, I have charted out the standard materials and how I&#8217;ve manipulated the parameters under each material, leaving out any parameters that are left at their default values.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>Some Maya shaders get quite close to the aiStandard results. Brushed metal effects are more subtle in aiStandard. The biggest difference is seen in the relatively poor results in Maya shaders creating clear materials that refract. The Maya clear glass looks like a thin wall soap bubble, but the aiStandard has a robust and physically accurate <strong>index of refraction<\/strong>&nbsp;(<strong>IOR<\/strong>) and complex internal reflections.

id=\"Taming_Arnold_noise_and_render_times\"><\/span>Taming Arnold noise and render times<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>One liability of Arnold is its propensity toward generating noise: granular texture where smoothness is the goal. This is discussed in the <strong><a href=\"https:\/\/support.solidangle.com\/display\/A5AFMUG\/Arnold+for+Maya+User+Guide\" target=\"_blank\" rel=\"noreferrer noopener\">Arnold for Maya User Guide<\/a><\/strong>. Where ordinary radiosity sampling is handled in the Attribute Editor tab, in Arnold we head elsewhere.<\/p>\n\n\n\n<p>The frustrations early adopters of Arnold had with intrinsic noise have been addressed in the last couple of updates to the software.&nbsp;Here we introduce a much-improved, time-saving workflow using <strong>Arnold RenderView<\/strong> and  <strong>Arnold Denoiser (noice)<\/strong>. It will feel extremely technical at first, but it&#8217;s a technique that, once learned, will save you WEEKS of render time. I&#8217;m not kidding!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Our_case_study\"><\/span>Our case study<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Though Arnold has vastly improved as a rendering solution since it replaced Mental Ray in 2017, it&#8217;s still a dark and dirty rendering engine. Pumping up samples, blasting lights, and generating impossibly long render times seemed the only solution. I really missed <a href=\"https:\/\/www.autodesk.com\/products\/mental-ray-standalone\/overview\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Mental Ray<\/strong><\/a>! However, the introduction of NOICE as a post-processing solution to eliminate noise \u2014 those dirty-looking shadows and speculars \u2014 has made Arnold my favorite renderer now.&nbsp;<\/p>\n\n\n\n<p>If you stick with Arnold lights and Standard Shaders, and apply NOICE in post, the pesky noise or &#8220;fireflies&#8221; you almost always encounter in Arnold are not hard to eliminate. Our goal is to do this without creating impossible render times. In this case study, we&#8217;re aiming for a high-resolution video render in about a half hour or a large-scale print resolution in under 4 hours. Can it be done? By following the workflow in this case study, we can significantly reduce render times for high-quality output, even in challenging ray sampling situations.

Our scene is formally simple, but to get good micro-beveling and smooth curving surfaces we need to indulge in a high polygon count: there are 50,000 faces among all the objects here. In addition to the ground plane, I have modeled a sphere using default sub-divisions, a cube with micro-bevels, and a cup with liquid. Both cup and liquid are based on cylinders with default sub-divisions, though I added a couple of subdivisions for the caps to help give the cup bottom the roundness of mass you see in fine glassware.<\/p>\n\n\n\n<p>A few modeling tricks here have implications for rendering quality:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>All geometry is smooth mesh previewed. This effectively increases the polygon count 16 times! But for smooth bevels at corners, we require a smooth mesh preview (3 on the keyboard).&nbsp;<\/li>\n\n\n\n<li>The liquid is boolean subtracted to fit tight to the interior of the glass, but then <em>scaled up 1.01 to intersect slightly with the glass for refraction.<\/em><\/li>\n\n\n\n<li>Because the boolean will double faces, reduce the radial polar effect by deleting edges and vertices incrementally, leaving only a few radial edges at the center. This takes time to do but will eliminate unintended ripples in the highly reflective and refractive surfaces when the smooth mesh is previewed. Download and inspect the sample file to see this.<\/li>\n<\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure

So for this case study, <em>I&#8217;ve deliberately placed lights closely<\/em> so that we have this problem to solve.

The number of samples can drive quality: too few and you&#8217;re guaranteed to have dirty, noisy shadows and specular highlights, too many and you&#8217;ll wait days for a render.

If I wanted a medium-size print that would fit on a 16 X 10 paper stock with about a 1.5-inch border all around, I&#8217;d approximately double the pixels to 3840 X 2160. If I want a large poster-size 16 X 20 stock with a half-inch border, I need to cover 19 X 15 and need 5760 X 4500, approximately doubling the size again.<\/em><\/p>\n\n\n\n<p><em>The ramifications for render time in this case study are that the HD video resolution will take about 30 minutes to render, while the medium-size print would take 4 times that long or two hours. The large print here will take about 4 times that, or about 8 hours! That seems long but these are not unreasonable rendering goals given the quality we want.&nbsp;But, as we&#8217;ll see, even these times are not sufficient to get rid of inevitable noise in the shadows and speculars. How can this be solved? Denoising in post-processing, as we&#8217;ll see!<\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Battling_noise\"><\/span>Battling noise<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>When trying to solve noise issues, most people reach for the low hanging fruit and dial up the Sampling Camera (AA) settings. This works in the same way that using a sledgehammer can swat a fly. Your&nbsp;computer will hate you for making it take days of processing time just to get rid of a smudge of noise. You could be more nuanced and dial up the Diffuse and Specular settings, but this is almost just as inefficient. Just doubling the AA settings from 3 to 6 more than quadruples our render time from 30 minutes to over 2 hours! And the large poster resolution jumps from an 8 hour effort to a processor-murdering 32 hour marathon! <\/p>\n\n\n\n<p><em><strong>And<\/strong><\/em> there&#8217;s no real guarantee that the noise will be eliminated at this sample size. Just imagine the week-long frustration-fest you&#8217;ll endure when you realize it takes an AA setting of 10 to defeat the noise in the indirect specular highlights!<\/p>\n\n\n\n<p>So we&#8217;re just going to leave Sampling at the defaults.<\/p>\n\n\n\n<p>With Ray Depth on the other hand, we have no choice but to tweak higher. Why? Because this can limit what can be seen. For example, low Transmission or Transparency Depth numbers here will just block out those phenomena from rendering at all. Instead of seeing through liquid and glass, which is about 6 layers, you&#8217;d just see black. So a rule-of-thumb setting here? Get the three Ts \u2014 Total, Transmission, and Transparency Depth \u2014 somewhere around 10 or 12. See these example settings:<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column

My only criticism of Arnold RenderView is that it exaggerates saturation of color, so understanding this you know to really inspect color by opening any file you create in an image editing program. By using the dropout under the window menu, you can inspect the different AOVs you loaded above to determine where your noise problems are. In our case study, it&#8217;s evident that the diffuse indirect and specular indirect are the culprits. We run a test render here at 50% size and the noise is evident. It&#8217;s a 15 minute diagnostic move that saves time later.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><a href=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM.png\" target=\"_blank\" rel=\"noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"645\" data-attachment-id=\"1969\" data-permalink=\"https:\/\/williamcromar.com\/newmediawiki\/material-culture\/screen-shot-2022-07-26-at-6-10-07-pm\/\" data-orig-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM.png\" data-orig-size=\"3868,2436\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Screen-Shot-2022-07-26-at-6.10.07-PM\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-1024x645.png\" src=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-1024x645.png\" alt=\"\" class=\"wp-image-1969\" srcset=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-1024x645.png 1024w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-300x189.png 300w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-768x484.png 768w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-1536x967.png 1536w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/Screen-Shot-2022-07-26-at-6.10.07-PM-2048x1290.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\"><em>Arnold RenderView: use it instead of Maya Render View in all cases&nbsp;<strong>EXCEPT<\/strong>&#8230;<\/em><\/figcaption><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>We could use this intelligence to raise the sample numbers for Diffuse and Specular, but let&#8217;s try an even bigger time-saver instead.

This is fixed very simply in Photoshop by opening the .exr file, adding a layer underneath, and filling the layer with black. From there, you can save a .tiff file, and for presentation, you can export a .png or .jpg. such as the one we see at the top of this title.<\/p>\n\n\n\n<p>Earlier in this title I mentioned a preference to render darker and tweak the results to the actual exposure level in Photoshop. This is roughly analogous to the &#8220;push and pull&#8221; darkroom techniques of photography. &#8220;Pulling&#8221; your film reduces contrast and brings out details in shadows and retaining highlights, which can then be manipulated creatively in the darkroom to the desired result. If the rendering process is like shooting a roll of film, the tweaks in Photoshop are like developing and printing the images.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_logic_of_lower_exposure\"><\/span>The logic of lower exposure<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>The logic is that lower exposure renderings tend to have more information in them, particularly in the lighter areas of the render such as specular highlights. It&#8217;s really difficult to restore information to a pure white or pure black space, so setting materials and exposures to avoid these extremes helps. Still, the tweaking that goes into a render setup can seem to be endless, and there is a diminishing return in attempting to perfect the settings in Arnold alone.<\/p>\n\n\n\n<p>After finishing the rendered sample images above in Photoshop, I manipulated them as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In <strong>Image > Adjustments > Exposure&#8230;<\/strong> adding a <strong>Plus 1.0<\/strong> preset<\/li>\n\n\n\n<li>In <strong>Image > Adjustments > Curves&#8230;<\/strong> pulling the white curve anchor down from 255 to 245<\/li>\n\n\n\n<li>In <strong>Filter > Noise > Add Noise&#8230;<\/strong> adding a tiny value (0.6 in sample)<\/li>\n\n\n\n<li>In <strong>Filter > Blur > Surface Blur&#8230;<\/strong> add low <strong>Radius<\/strong> (1 in sample) and low <strong>Threshold<\/strong> (10 in sample) if I  need to reduce noise but keep sharp edges<\/li>\n\n\n\n<li>For printing only: <strong>Filter > Sharpen > Unsharp Mask&#8230;<\/strong> to compensate for ink spread at edges in a print. Values for this sample would be about 50% <strong>Amount<\/strong>, <strong>Radius<\/strong> 2 pixels, and <strong>Threshold<\/strong> of about 5 levels. Unsharp Mask always looks a bit alarming on the monitor, but it helps keep a print crisp by increasing edge contrast.<\/li>\n<\/ul>\n\n\n\n<p>These refinements might take forever in a rendering engine if they are even possible. In Photoshop, they take minutes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Your_turn\"><\/span>Your turn<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Return to the Maya scene file in the scenes folder of your Nine Square Grid exercise.&nbsp;<strong>COPY IT<\/strong>, rename the file&nbsp;<strong>yourname_nineSquareGrid_materials.mb<\/strong>, and open it to apply a variety of uniform materials.
