Luke ….. not sure what face is which color based on your style but if you click the face(s) in question and look at the Entity Info window it will show two faces with a material stacked over each other. The top rectangle representing the face is the top side, the lower rectangle representing your face would be the inside face. Hope this makes sense
What’s happening fellas! The orient faces style switches to a “shaded using all same” mode, then colors the front of the face pink, and the back green. It is ideal to see all pink if you are trying to render. If you see a green surface, right click and reverse face… Keep in mind you might need to apply the material to the other side. Just a troubleshooting strategy that nets more predictable results. I hope that helps!
