Some strange shadows appears on custom geometry


When i import my meshes to a ue4 scene and rebuild lights, some strange shadows appears.
I have tried to calibrate lightmap resolution, uvw map to fix this but couldn’t.
How can i fix this problem?


It has overlapping UV’s. Check out tutorials on the web for lightmap UV’s.

As said, the mesh has overlapping uvs -> you can fix that with a 2nd uv channel:

Here is also a good site for light/shadow problems: ://www.worldofleveldesign/categories/udk/udk-lightmaps-05-common-problems-solutions.php

Thank you very much. I will watch tuts and try this.
