skatter material filter

Hi
I’ve dabbled with assigning skattered objects to a specific material but it doesn’t seem to be functional. I’ve tried all probability percentages and unclicked and clicked all skatter objects but it doesn’t make a difference. I maybe missing something, I’d appreciate your feedback.

Do the objects already have a material applied to them?

The random material feature in Skatter works the same way as applying a material to a component or a group in SketchUp: only the blank faces in the components will receive the material. If faces already have a material, their material cannot be replaced.
