Corner making a tri face On the edge of my model I'm trying to eliminate the tri face it's making. If I do a knife cut vertical, it'll make a quad, but if I go horizontal it'll make a tri face. When I add the subdivision modifier, it seems like a much cleaner topology. Is there a solution when it comes to avoid the mesh from making a tris?
You don't need the knife cut at all :).
Just inset the corner slightly, it'll move the ugly quad out of the way.
The corner is now smooth, and you can add more loopcuts to make it sharper.
