Reimporting Mesh - Lightmap UV Problems

Hi Guys, Im having some problems here.

I Import my mesh, Later, just to keep the work. Than, i create on the mesh the UV 2 for lightmao, than I reimport the mesh on UNREAL.

But, the when i need to do build, keeps saying that have overlap on the UV, but doesnt. The UV its Ok.

When i Delete the mesh, and Import the file again, everything is fine.

Am i missing somnething here?

Thanks!

Hi dneobr,

Check the Lightmap Coordinate Index in the static mesh editor and make sure that it’s set properly.

If you Open the Static Mesh Editor then go to the static mesh settings you’ll find the setting there for the Lightmapp Coordinate Index. You can make sure that it’s set to the correct UV channel for your lightmap. This should typically be set to 1 for the lightmap.

The build settings in your picture are just settings that you can change and apply. These do not directly impact the actual settings that are currently set unless you change something and hit apply. These are to make changes after the fact.

I used the Coord. Index to 1. Still no changes. Just replacing the mesh does it.
