I’m trying to import DexSoft’s Castle model into Unreal Engine 4. I’ve used Blender to add my own lightmap UVs to all meshes and set the import options accordingly:
- LOD0/Build Settings/Generate Lightmap UVs = Off
- LOD0/Build Settings/Source Lightmap Index = 1
- Import Settings/Generate Lightmap UVs = Off
However, when I build my lighting, I still get the message “Lightmap UV are overlapping by 96.5%. Please adjust content - Enable Error Coloring to visualize.”
The file contains multiple meshes and each mesh is UV mapped on its own. Could that be the problem? If so, how do I fix it? Do I have to join all the meshes together?
