I have some objects with bad uvs. I like to fix them within the editor. I’ve done that before with an earliere engine version.
But with the current version it is not working at all!

The new UV channel just stayes empty and there is never any new uv generated.

What can I do about it. It has to be done in the editor.

A new UV should have been generated but channel just stays empty no matter what.

Try to set destination lightmap index to 1 as I think in UE you can’t have situation like this: CH0 used, CH1 empty, CH2 used…
