Those textures will be used in a Material, and the Material will be assigned to the mesh.
In a previous video I saw you had a Material set up, It looks like the materials for your mesh already exist but are white.
So open up ‘GeneratorMat’ and use that “Albedo” texture as Base Color. Compile the material and you should see the mesh update.
It’s an older tutorial, but if you watch this series you’ll level up.
