NoteWhen baking light
maps using mental ray some of the built-in texture filtering features
in Maya can be of great help. For example, when a texture bake operation
has been performed, go to the File Texture node
in the shader network (by default connected to the outColor channel
of the assigned SurfaceShader) and under the Effects tab
in the Attribute Editor adjust interactively using
the Filter and Filter
Offset controls (the Filter Offset control
is very sensitive and is effective with values in the 0.05 range)
to get the required smoothness. This may then be converted to an
unfiltered texture by using the ConvertToFileTexture procedure.
