How do I convert an obj with multiple materials?

[HappyAlexRomania]

I'm new to blender and can't figure out how to merge materials and textures together. Is there a way I can use an obj that has an mtl file to convert it into a minecraft model?

materials are not supported in objmc. you will have to bake it all into one single texture as input to objmc.
