I am working on a new robot modell. Hip and Chest are not allowed to bend (bend 0) while only do abdomen remains flexible (bend 1) But now I have a little problem : When I bend the abdomen (any rotate will do) it is perfect. (Picture 1) But if I move the Chest part it looks like it has no effect on the abdomen at all (picture 2) How can it be ? (Hierachy looks fine) Additional question : Is there a parameter in the cr2 file like "welding strength" ? If I bend the body too much the edges of the body part move a bit out of position. I don't want this. thanks Holli
