This is why we do test renders.
I did some to test my window cuts in the teardrop. You can see some slight “pinching” around the round window in that last pic. This is caused by the angles of the faces and a few other things. I’ve got a plan to fix that, but if it doesn’t work I may just have to take that window out. Fortunately, I have an incremental save file with the unmarked teardrop, so I can just delete the window and then replace those faces, then try it again.
