UV Distortion

I’m trying distort my UVs to get some desired effects. Everything looks good in preview viewport but if I plug it anywhere the editor crashes. Any solution or explanation would be appreciated. Thanks!

That’s a cool looking effect.

However the answer you seek is in your error message log.

Also, try removing different branches, to reduce computation. See what happens. You should be able to isolate the issue.

From my perspective, the Sine/Lerp branch might be expensive, but I wouldn’t expect it to crash. Maybe it’s a large mesh with a lot of verts?
