Transform tools will not move points or hulls...
I am building the Red Girl tutorial. (actually I'm just winging it and playing with NURBS spheres). After successfully bringing up CV's and moving points around, I've detached a mouth part and selected the inner hull and prepared to push the hull inward to form a mouth. Suddenly my Transform tools will not move the points/hulls. When I click the mouse on the tool it grays out. What have I done wrong?
