Value Error('unknown file extension:') error for some gltf files #175

Open shyam98 opened 4 years ago

I export fbx or obj files from Solidworks visualize then using blender to convert them to gltf. When taking those gltf files and running them through gltf2usd I get this error. Let me know if here is anything I can do to fix this, thanks! (The glTF files look perfectly fine and have textures as well)

Have same issue here with blender 2.8 gltf files

So I found solution that works for me!

When export from blender to gltf You need to choose Format: glTF Separate(.gltf + .bin + textures)

Then gltf2usd sript will work as it should!
