vertex map displace

[koubankeo]

When I want to use vertex map as a mask, displacement does not work.

Corona Renderer 6 for Cinema 4D (Release Candidate 4)

Hi, usually displacement is only taken from the first material, that's why you are getting no displacement at all, because the displacement map from your first material is a black color map.
You can try mixing the displacements at first material using the same masks you're using to layer the materials. (see attached images)
I hope this can help you.
Regards.
