RENDERMAN SHADERS, SLIM TEMPLATEs

# File: v3d_cGatherMegaAovDynamo.slim # # Description: Render separate surface attibute (aov, shading component) each in separate relative AOV. # All perform in 1 (ONE) shader tracing call, get banch of it FAST. # Access to full render pass control in post! Automaticly create new AOV, like if we need "DiffuseDirect", we get "_reflect_DirectDiffuse" pass. # What if we have incandescence in primary pass AND reflection - on post we turn off incandescence, but it stay in reflection.... with this template you get full control. # All pass in list generated, first use as output of template (first visualized). # Can be used with reflection and refraction! (even get multiple ray depth, self reflect/refract) # Very powerful feature. # # Usage example: # (dont forget raytraycing on) # Create delux shader. Add Rim and Incandescence (and connect texture to color value). Attach it to sphere. # Create constant shader, connect this template to color and attach to ground plane below sphere. # In "What to do" field add 'Rim' first. # Now by default we trace 3 variables - Rim Incandescence DiffuseDirect. For each of this automaticly created new AOV's. # By "aovPrefix" field on output can be catched new AOV: _reflect_Rim, _reflect_Incandescence, _reflect_DiffuseDirect. # (if use refraction vector, "aovPrefix" can change to _refract_ or anything what you want) # Add this names (color _reflect_Rim) to "channel" and "secondary display" in Renderman Globals.... All done.

# File: v3d_cCatchLightOutput.slim # # Description: Catch AOV variable casting by light. Like render diffuse and get shadow pass, L direction pass, # or any you like to send (it even can be pattern or texture map) # # Usage: Attach AOV to light (in my shader in separete slot), or colorAOV and light send it. # Or produced output in standart lights shader is: # color: _shadow, _cl_noshadow # floats: __nondiffuse, __nonspecular, # _contribRim, _contribThinTranslucence, # _contribBackScattering, _contribSubsurfaceScattering

# File: v3d_cCatchLightOutputAOV.slim # # Description: Same as v3d_catchLightOutput.slim, but in DynamicFunction can resend AOV without extra nodes. # Catch AOV variable casting by light. Like render diffuse and get shadow pass, L direction pass, # or any you like to send (it even can be pattern or texture map) # # Usage: Attach AOV to light (in my shader in separete slot), or colorAOV and light send it. # Or produced output in standart lights shader is: # color: _shadow, _cl_noshadow # floats: __nondiffuse, __nonspecular, # _contribRim, _contribThinTranslucence, # _contribBackScattering, _contribSubsurfaceScattering

# File: v3d_envLatlLens.slim # # Description: Render environment latitude/longitude map from camera. Render in float and get HDRI environment texture. # # Usage: Create plane geometry in front of camera, attach constant shader to plane (you can parent plane to camera and off visible in reflection etc. parametr on shape)

# File: v3d_cNormalTangent.slim # # Description: Convert tangent space normal map to camera space normal. # # Usage: (convert to normal) and attach to custom slot in displacement, or input normal in diffuse function etc.

# File: v3d_cShadowSoftOcclusion.slim # # Description: Ultra-fast soft shadow rendering (with highest quality!) by using occlusion. Original idea from Dmitry Novikov. # # Usage: Connect to light shader "shadow" slot (or custom output slot from my shader and catch from surface).

# File: v3d_cPostEnv.slim # # Description: Generate coordinates to use in IBL or add reflection in 2D. # Mode = 0 - for reflection # Mode = 1 - for image base lighting # # Note: Image base lighting in this case may not very accurate, # because in 2d looking 1 sample from coordinate image. # For example, coord. can render in double resolution with low sample, and resize it down after add reflection ("antialiasing" in post, course image file size much bigger). # # Usage: attach to AOV and render it, combine in 2D package with appropriate script/macros.

# File: v3d_fMultiMapZbrushManual.slim  # # Description: For ultra high detail displacement map, like 10 maps in 4096*4096 pixel resolution (total 40960*40960, without one huge image), # when using Zbrush and MultiDisplacement (model separated to groups with > 0-1 UV space) # UV groups must be in U direction (for simple managing). If you need more 10 set, create second copy and set offsetU value to start position. # # Usage: Map 1 = UV 0-1 (U), Map 2 = UV 1-2 (U), etc.

# File: v3d_fMultiMapZbrushAuto.slim  # # Description: For ultra high detail texture map, like 10 maps 4096*4096 pixel resolution, in total 40960*40960, without one huge image, # when using Zbrush and MultiDisplacement plugin to export texture (model separated to groups with > 0-1 UV space) # UV groups must be in U direction (for simple managing). Can set offsetU value to start U position if uv starts not from 0-1. # Updated dynamic version - select one map and other regions maps be connected automaticly. No tedious selection of 101 texture map by hand. # # Note: if you using Zbrush (current MultiDisplacement3 export plugin), you can view very small seam between region changes. # To remove it a little bit scale down uv shell border in Maya. File number index must start from not zero (not name.0000.tif) # In Zbrush set '.' after texture name (name. ) and all other naming convention must right. # # *.bat file example to batch convert files to tex # for %%t in (*.tif) do "%rmantree%/bin/txmake" -float "%%t" "%%t.tex" # # Usage: select 1 texture map and all other be automaticly connected. (used mask - fileName.#.extension)

# File: v3d_nBumpedNormal.slim # # Description: bump normal, can create cool effect like underlaying layer lacquer surface (polished wood etc.) # # Usage: Primary use with delux component to achive one bump map on diffuse and different bump map on specular etc.

# File: v3d_xMegaAOV.slim # # Description: Connect multiple AOV to surface in one time. Can view separate AOV. # # Usage: Connect and give name to AOV channel. This map not need used in primary shading, is need only be attached to surface and calculate in "backgroung". # For example attach to AddFx surface.

# File: v3d_fMultiBlendShape.slim # # Description: Add different Dispacement map value depend on blend shapes, like wrinkle on face when smile, different map when angry etc... # # Usage: use mel script - v3d_multiBlendShapePrimvar.mel, on proc call change name of blendshape node and target surface name # (multiBlendShapePrimvar pCubeShape1 blendShape1;) This create primvar on shape node (also print names in output) # copy this names line by line to "Attribute name" field and connect associated texture. # # To do: may create full automatic, get file names - file.'blendshapename *'.tex - and auto generate all texture() call * read primvar # but it cause not able select custom multiregion texture etc. depend on production think about name convention.
