My apologies, I get it now
Well, the Forest Material
is designed mainly to be used on "billboards" and to add color variation on 3D objects, we highly suggest to use the Forest Color
map. When using Multi/Sub-Object
materials, the Forest Material
needs to be applied over each of those Multi/Sub-Object
materials as shown on attached screen-shot.
Anyway, in your case the easiest way to archive the desired look (and get corresponding Render Element values) would be to apply the Color Tint
directly under the Material
roll-out of the Forect object (which will propaget to the VRayDiffuseFilter
Render Element correctly).
