Trying to Make Sphere with Texture on Inside

I’m trying to make a sphere with a texture mapped to the inside in Unity. I started out by using boolean modifiers to cut a sphere out of another in Blender to make a hollow sphere. Then, I exported it as an fbx into Unity. However, whenever I try to apply the texture mapping (with Albedo), the actual model does not change at all.

Never mind. I solved this problem. Here’s what I did for anyone with a similar problem: I used a sphere game object and added this script to invert the normals so that the texture was on both the inside and the outside of the sphere.
