GPU Lightmass does not take the second UV Channel

Hello,

after some testing, it does not seem like UE 5 takes any other UV channel, than the first one, in GPU Lightmass.

This is really annoying, because now we have to use other UV channels for texturing.

Hopefully this isn’t just a bug for me. Hope this gets fixed soon!

Cheers

So now I found out, this is only the case, if you use objects created with the new Modeling Mode. Somehow they don’t seem to work with UV generation from the Modeling Mode UV section or the “Generate Lightmap UVs” process.

Exporting them to another 3D software and importing them did the trick for me.
