Does anyone know how to move UVs 'smoothly'

Hi all, I’m trying to move a 20-30 vertices islands around a (1024*512) uv map, but for some reason they all move jerkilly (128px or 64px depending on the direction, up or down), is there a way of doing it smoothly?

Sounds like you have snapping on

Ah, yes, that was it, thank you :smiley:
