Attempting to load OBJ + MTL of the Earth (not my model). I am using the template provided in the examples. OBJ (sphere) will load, but it is grey with no material/texture. The blender file will load the material properly. I have looked at other solutions such as Loading models problem (OBJ + MTL or FBX) to no avail. Provided HTML below.

I have a feeling there is an issue within the MTL file itself which I will post below.

It seems there should be a file path somewhere linking to the actual images, not 100% sure though as I am new to this.
