Issues importing models with textures for use in a GridMap

Godot Version

4.3

Question

I am at my wit’s end trying to import a model into Godot so I can use it in a GridMap. When I import the model as a .obj file, it does not have a texture. However, when importing it as a .glb file, it does have the texture, but it can not be used for the GridMap. How do I fix this?
