It seems like I don't know how to structure the geometry around this kind of connection.
I've tried a few different methods, all got some sort of distortion. I've also tried to match exactly the topology of the video, still got some distortions.
what should be the flow in this part?
Hey kkoko0 , here's what I've got in that area:
You can also check the revolver source file in the downloads and use that to compare. My guess is that the edge loops directly above and below those poles help to keep it from skewing like that, but I'd have to check your file to be sure.
Keep up the good work!
