I am trying to sharpen these edges without getting the overhang artifact you see in the image. I was using the bevel modifier that works for some of the edges as seen in the picture. A loop cut helps this particular edge, but it also sharpens the outside wall of the model, which I don’t want - and my topology isn’t built well at all for edge loops (I had to do a lot of things to avoid tris and n-gons)
If I need to retopologize, I will. I would use tris if I needed to and doesn’t hinder the result but n-gons are not an option. If it’s helpful to know, I am going to bake this hi-poly res model to a low poly version.
