I was wondering why, while in Projection Master, I can scale and move but I can’t rotate. My settings for Projection Master are ‘Deformation’ only and everything else is turned off. I’m using Single Layer Brush in Tool palette and DragRect stroke for the alpha.
I imagine there are technical reasons but you can use the Directional Brush instead - Rotate will then be available.
Thanks for replying marcus!
If I use the Directional Brush then I can’t ZProject the alpha onto the canvas. If I use the Single Layer Brush to ZProject the alpha onto the canvas then switch to Directional Brush, Move, Scale and Rotate are active but don’t do anything to the projected alpha.
OK! Just found out that you can’t use DragRect stroke if you want to Rotate. If you use Dot. DragDot or Freehand strokes then rotate is available, but I still don’t understand why it isn’t available for DragRect. The other strokes work, but not very well because the ZProjection keeps disappearing while transforming.
Just discovered something else. I can use DragRect stroke if Normalized is on in settings. Then Move, Scale and Rotate all work…but…the zprojection still keeps disappearing while transforming. It’s not that important for Moving but it is for Scale and Rotate…grrrrrr!
Oh! This is in ZBrush 4 BTW.
Yeah, that’s a long time irritation. 
It can disappear altogether - one tip, switching to a different brush while the stroke is visible will mean it stays.
