How to save UV template?

Godot Version

3.x and 4.x

Question

With a MeshInstance selected I can click on Mesh/View UW1. How can I save that as a file so I can then work on texturing meshes I created using CSG?

I don’t think you can edit or copy-to UV data to CSG shapes or MeshInstances in Godot, the vertex count has to be same for the UV data and the proposed CSG/Mesh.

In the Scene dropdown menu you can export a CSG scene to a GLTF file which will only contain the final mesh data, this can be textured in other programs that can load a GLTF file like Blender, does that work for you?

I thought about that as an alternative and I believe it would work. But that requires a few extra steps and learning blender.

I was hoping to be able to just save that preview the Godot gives you right in the editor to an image file. I even tried taking a screenshot and using the screenshot and I believe that would work for me but the resolution is a little small.
