V-Ray provides support for the texture baking mode of 3ds Max. You can
use V-Ray as a texture-baking renderer; however since VRay does not support
the standard 3ds Max Render Elements, you need to use the V-Ray specific
ones (e.g. VRayCompleteMap instead of
CompleteMap etc).
It is recommended that you set the Secondary rays
bias from the
Global switches rollout to a small positive values when doing texture
baking. This wil avoid some artifacts on the edge padding. V-Ray will
automatically assume 0.001 as a
Secondary rays bias, if you have accidentally
left it to 0.0 in texture baking mode.
