This is exactly the tool I have been looking for! One question: when importing the .obj file into Godot, the mesh looks like it's inverted or something. All faces facing the camera are invisible (...is the best way I know how to describe it)
I'm not familiar with Godot, maybe it expects vertices in the opposite order? Last time I checked (long time ago:)), this imported fine into Blender.
Yup! As an update, I disabled the rear-orientation culling setting on the mesh in Godot and it was immediately fixed.
