Title: Displacement in corners
Post by: jarekhell1 on 2019-06-06, 09:53:03

Hello,
i have a problem with displacement map in the corners. They look bad, as if they are open. What should be set or what model to make it work well?
Disp set to 10cm.

Displacement relies on the underlying geometry and only displaces in the direction of the normal. If you have polygons that are at right angles to each other, then the direction of the normals are at right angles which creates what you are seeing. One solution is to add a bevel to the edge with a few edge loops to allow enough angles between the faces to appear like it is smooth.

Make sure your vertices are welded in the mesh/poly. This should solve the issue

-chamfer your edges
-make sure UVW mapping is correct (ideally the texture should not be cut on the corners)
