Mental ray rendering fur with passes

Whatewer you use- maya fur, or shave and haircut - rules and workflow will be the same. 1) NEVER USE RAYTRACE WITH FUR! Any rule you can violate, if you understand them clearly. This is not exclusion-if you need to render fury sphere with 10 000 hairs- no problem: turn on FG, soft raytrace shadows, use occlusion and nothing terrible happend. But when you will have deal with real fury character, grass or any other scene with a lot of fur- raytrace can cause more headache then bennefit. 3) Render with RASTERIZER. 4) Render with puppet shaders pack. I will not explain how to archieve desired appearence of fur. Now set render type of your fur to hair primitives. In render globals Set primary render to Rasterizer and turn off raytracing. Now shading of fur defined by shave an fur inside engines. For maya fur: Create p_shader_replacer geometry shader. create polyCube, check "enable geometry shader" in mental ray section of TRANSFORM node. Now its time to setup lights. With one key light: Scene

How To Render Wireframes With Ambient Occlusion In Maya, Using Mentalray More often than not, students come to me asking for a good method of creating wireframe renders, so in this tutorial I'm going to explain two different methods of achieving a wireframe render with Ambient Occlusion in Maya using Mentalray. Step 1 This is the model I'll be using to create the Wireframe render with Ambient Occlusion. Step 2 Since I'm going to be using Mentalray for this tutorial, make sure it's loaded in Maya. Step 3 From the Plugin Manager window, check the 'Loaded' and 'Auto load' options for "Mayatomr.mll", to enable it. Step 4 Now open up "Hypershade", by going to Window>Rendering Editors>Hypershade. Step 5 Click on the 'Surface Shader' as shown in the image below. Step 6 Now from mental ray’s "Textures", click on "mib_amb_occlusion". Step 7 Middle mouse drag and drop the "mib_amb_occlusion" onto the surface shader created in step 6, and select 'Default' from the options box that comes up. Step 8 Step 9 Step 10 Select "mental ray" as the renderer and hit render. Step 11 Step 12 Step 13
