Check this out as Keifer kindly taught me:
These were made by two distinct Exports form Mathematica to .OBJ format, I only uploaded the .OBJ twice and then chose materials and etc. for each instance.
Now this a single Export from Mathematica https://clara.io/editor/b4321b35-9758-4d69-8f2d-0032c1550994
But the red part was assigned material in Mathematica and I then uploaded the .mtl file through Clara manually and something is not working.
This is now a problem with Mathematica not a Clara issue.
I do not know how to delete this post
