Godot version

3.5.stable.official

System information

Windows 10, GLES 3, RTX 2080, i7 6700k, 24 DDR 4

Issue description

I created UV2 for all my tiles inside of a blender, so godot sees them as UV2

I ticked "Use in Baked Light" for all tiles

I exported meshlib

I restarted godot editor because of this bug #26775

Then I created BakedLightMap over the thing

press Bake Lightmaps

It says this

Steps to reproduce

Create gridmap, create UV2 map for all tiles, check Use in Baking Light.
Then add tiles in world, try to bake

Minimal reproduction project

No response
