I’m getting these artifacts with subdiv on. They are created whenever I create lines between 2 points with CTRL-F. How do I fix this? Thanks in advance!
EDIT: I took the subdevide off and I see that its a problem with there being geometry with unmarked edges created inside the lines i’ve already made. No idea how to fix this. i tried dissolving the faces with unmarked edges and deleting them but it didnt work: probably because that’s not how you fix this. Thanks for the help!
