Hello! pretty new and fresh 3dcoat user here, I'm following a long a tutorial by Robert Demptser "3DCoat | Modelling and Texturing" on youtube where he is making a circular selection using the pose tool. I tried everything but whenever I select posetool > e > select circular selection, backfaces non checked and every other setting he has is identical but nothing happens when I drag a selection circle. I can still select using the square, rectangle, freehand, polygonal etc. It just seems to not show up / work! Every other tool i've tried seems to work using circular selection except for the Pose tool. Is circular selection somehow disabled by default?
