Re: importing mtl file
I have the same issues with my files I downloaded from https://www.cgtrader.com. I am not able to find the exact link but here are some code-snippets (I hope they are helpful). Here are the first lines of my obj.file which has more than 19.000 lines and 13MB (it's a tree).
mtllib OC12_1.mtl
# object OC12_1

I also have several tif-files. Both mtl- and obj-files are in the same zip-folder when importing, but colors are not imported.

Please help me :)
Thanks in advance.
