Long time issue with uv maps
Every so often when I am making an object my uv maps go whonky. The task bars become greyed out (unresponsive), the lines and faces will not stay selected if you move the cursor away and there are blue dots around vertice intersections. I find that the points are not weled (the blue dots) and I have to manually target weld in the uv map area each bue dot.
I am in the middle of a large project and it is taking me forever to hand weld each of those blue dots.
WHY does this happen in the first place? Anyone know what is going on or how to stop it from happening? Thanks in advance.
I'm attaching a pic but the dots are hard to see.
