Rotate and Move UV islands do not affect all points


I’m trying to rotate / move UV islands.

It does work, but some points are not affected. This results in a smearing effect.

I have uploaded a video here to show what this looks like:


Can anybody tell me what might be causing this and how to get rid of it?

Btw, I have turned up “Automasking by Polygroups” and I selected 100.

Thank you very much!

Hello @AC2015

Some of your points appear to be masked. Clear any masking via Tool > Masking> Clear, or ctrl-dragging a masking marquee in empty canvas space. Your auto masking setting will also influence which points you can affect–disable it if your issue continues.
