Generated Lightmap UV2s disappearing

Nacoleptic

Hello Godot Community!

using the BakedLightmap node i have an issue with the generated UV2s.

I'm importing a .glb file from Blender and setting it up as a .tscn oder .scn I generate the UV2s like this: Everything works fine.

Now when i restart the editor, and try to look at the UV2s they are no longer there:

I have tried saving as .tscn or .scn. Maybe i have my import settings for the .glb wrong but i couldnt get it to work. I found some similar posts about this issue but no solution worked for me so far.

Maybe you have some ideas for me! Thanks in advance.

I could be misrecalling and be wrong but I think your issue is with how you open your scene. Also make sure the node/object resource(mesh) in your scene is local to the scene.

Thanks for the reply. Making the Meshinstance Unique seems to have fixed my issue.

If you import the GLB/GLTF and select "Generate Lightmaps" this bug goes away. For some reason Godot will delete the UV2 maps at random times for no apparent reason.
