load and save glb meshes

[imperator-maximus]

Hi,

I made a very simple test workflow for just testing the load and save nodes:

I used a simple cube mesh for testing.

But I am getting in load mesh node:

Error occurred when executing [Comfy3D] Load 3D Mesh:

invalid index to scalar variable.

~~~~~~~^^^^^^^^^

Thank you

Thanks for testing, I'll add it into bug fix

Problem turns out to be one edge case when loading .glb file without albedo texture maps, it will be fixed in next release, along with many other updates to make the system more robust!
