Works as designed
Issue description
I made a model with blender and saved it as an .obj with triangulated faces. Whenever I put it in it worked fine until I loaded up Minecraft. Then the files textures do weird things and turn black. This is my first model so it is probably a stupid problem.
It might be a material issue. Minecraft supports a very limited set of materials. I can't really say for sure what works so you will have to experiment a bit, or ask on forums for other members to help.
