![]() Subsurface + Rim + Refraction + IncandescenceĪdditionally, there are "ancillary outputs" that are not used to create the beauty render but can be useful for other compositing tasks:Ĭolor used to scale specular illuminationĬolor used to scale ambient and diffuse illumination Result = SpecularDirect - SpecularDirectShadow + SpecularIndirect +ĭiffuseDirect + Translucence - DiffuseDirectShadow +ĭiffuseIndirect + DiffuseEnvironment + Backscattering + The recipe for compositing your beauty image is a simple additive process using these outputs: ![]() Total contribution of cheap/thin translucence Total contribution of subsurface scattering Specular light reflected from other objects (coherent reflections) (Unoccluded) specular response from environments Specular response that is shadowed, subtract this from SpecularDirect Total contribution of incandescent effects Unoccluded diffuse response to direct lightsĭiffuse response that is shadowed (subtract this from DiffuseDirect)ĭiffuse response reflected from other objects Total contribution of backscattering effects The total contribution from ambient light sources They all must be passed through layering operations. ![]() These additive terms are required to reconstruct the beauty render. To set up and a specific type of AOVs in Maya for certain compositing workflows. Refer to the AOV documentation and the Shadow/ReflectionĬollector Tutorial. RenderMan for Maya provides controls to generateĮxactly the kinds of secondary outputs required.įor more information about workflow associated with creating secondary outputs Secondary outputs can also be used toĬreate special effects. It can be more efficient toĪdjust certain effects in compositing (such as tweaking specularity) than Secondary outputs are useful for compositing. The same time the main image is being rendered These outputs are not rendered in multiple passes, but are created at Reflections, shadows, etc.) into separate image files, called secondary RenderMan for Maya can output additional data (specular highlights, Outputs (also called Arbitrary Output Variables, or AOVs). ![]() Another feature of RenderMan for Maya is the ability to generate secondary ![]()
