My game uses 3D level geometry imported from COLLADA files exported from Blender.
When I manually Unwrap UV2 for Lightmaps in Godot it works only in the engine viewports - as soon as I run the game, the .dae file is being re-imported, the UV2 mapping is gone and the lightmaps don't work.

If I discard instancing of my 3D scene - it will work, but I can't easily update my geometry from Blender export.

I'd like to be able to automatically unwrap UV2 fro lightmaps as soon as the COLLADA file is being imported so that I can have it instanced and use lightmaps at the same time.

How can I do this?
