Hi all, I've been working on this node based gltf viewer because nodes are cool af, you can check it on the link
here or you can go to this
demo link.
Its still work in progress so its in read only mode, you can inspect the scene but cant do any edits.

It would be really neart to have a UV examination view, which could show a UV wireframe on top of a texture. Or maybe even UV seams on the 3d mesh.
Switching to a custom 3d engine would open up more possibilities.
