I can’t build the lights for the new advanced lighting map coming with the 4.5

I ve got this error: Skybox Lightmap uv are overlapping by 50%

Any help?

Hey Maxxi -

You can open up the Skybox in the Static Mesh Editor and under Build Settings click on Auto Generate UVs and this will replace UV Unwrap 1 with an unwrap that does not overlap, make sure that the LightMap Channel is set to 1 in the Static Mesh Settings and you should not have this error again. I have also entered this in as a bug (UE-4534).

Thank You

Thanks for your answer Eric,
I auto regenerated uvs on channel 1 but still the same pb when I build the lighting!

Did you go under the Static Mesh settings and assign the new UV Channel 1 into the Light Map Resolution Channel?

I have this problem with a different mesh, and changing the lightmap coordinate index hasn’t affected the problem either.
