Feature description:

In order to properly view your extracted mesh, we need the .mtl file to see the applied materials.

One more thing I forgot to mention, this issue can also be fixed by allowing for exporting the mesh in either glTF or GLB format.

Ok, this should be the last thing I remember, when exporting to other applications like blender, I noticed the UVs are not correctly mapped, resulting in misshaped exported meshes (even with .mtl files from blender), this problem is resolved by using blender to export as GLB.

Take these images for reference, when put in blender, the entire top half is protruded:

I did not do anything but take the .obj file directly from the program over to blender
