don’t know how difficult it is to have option (check box) let the script animate into a flat. Specify number of frame for anim, and let the script rotate child bone to the parents direction (not sure if there are possibilities to specify that).
Anyway thanks for that I will try to test it for some crash deformations of object. Based on artist task Maybe it will be usefull for more things.
p.s.: A jestli uz mi neni rozumet v te me inglis, co chci rict, dej mi prosim vedet. Diky za vse.
