The following
describes the use of textures in RenderMan for Maya. Texture files are often used in shaders, as an alternative to procedural
textures.
Textures |
RenderMan for Maya accepts source textures in many image formats, including: TIFF, Alias, mayaiff, Radiance, JPEG, HDRI, and SGI RGB. RenderMan For Maya will maintain the precision of 32 bit floating point images by default.
Source images for texture maps can be any resolution; however, RenderMan's conversion process causes these files to be resized into various other resolutions for fast filtered access, each being some even power of two resolution in both width and height. To avoid resizing (and the consequential interpolation of your pixels) use resolutions with a power of two: 256 x 256, 512 x 512, 1024 x 1024, etc.
RenderMan handles textures very efficiently, and many textures may be used in a single scene. There is, in principle, no limit to the number of texture maps per surface.
