Although I did uvmap one (insert a picture to the model), the rest are just plain colours added to the model (yes I did assign them while in blender,) this should have worked, right? Also if I use a assign a material in blender to replace with an image, and after I export it I put the material and the mesh file in the correct folders, should I also put the referenced image in the texture folder? The error I get is file not found. But, I realized after reopening the game the next day that some of the materials that didn't work before work now. Now I still have the issues of meshes not showing as being two sided, and some colours still do not work after that.
