As you see on the Bob model with materials, there are some duplicate faces in the mesh messing things up. This week I started working on a minion mesh that is more cleaned up and has better edge loops for animation. However, I wasn't able to finish that mesh in time for this week, so the materials will be shown on the old meshes - nest week they will be finished for rigging.
New Mesh I have been working on.
I added material slots to my meshes and then added materials to the blueprints of the minions so they would automatically update.
