I don’t understand how to fix this, I made a few static meshes in Unreal 4 itself and I’m coming up with this error/problem. How would I fix this within the Engine? I tried looking through other answers, but came up empty.
Hi!
This happening, if your mesh not have secondary UV (UV1) for light map or in Mesh Editor → Details ->Static Mesh Setting → Lightmap Coordinate Index set to 0. It must be set to 1.
This also fixed my problem (using 4.9.2)!
However, it seems I have to set the index to 1 every time I do a new lighting build
as it gets reset back to 0.
Is that expected? / Is there any way to make the change permanent?
