I made a static prop that consists of several parts as *.cr2. There is a core part as parent and other parts that can be switched of (hidden) as children. These children should not be moveable, rotateable, scaleable,... They should only follow their parent. To lower the size of the *.cr2 and to get rid of the unwanted dials in the children I wanted to remove these channels in the *.cr2. I made some tests in between and it worked for the translate, rotate, scale and taper tiles. I do not know what can be done with the other hidden dials. Any idea?
