Blender Edge Flow/UV Mapping help needed I started a project recently with a sewer scene, and I'm trying to make a circular hole in the cylinder I'm using for the wall to make a ladder that leads into the sewer. However, when cutting the hole, I've been able to get some decent edge flow, but I can't seem to avoid UV stretching. Also, I'm using Adaptive Subdivision to raise the bricks, and for some reason it doesn't seem to be working all of the sudden (before I cut the hole, and sometimes when I was reworking the mesh it would work). Any help would be appreciated, thanks!



Here's the file (copy and paste the link into a web browser, the file was too large for blendexchange so I used my google drive):

I don't know anything about Adaptive Subdivision, maybe create a new question for this. About your first question: Your stretched texture is created by the ngons, You need to use quads instead, so just correct this and it should work.
