Hi,
THanks for the help, but it didn’t work. I got a funny rotation around some other axis (presumably the shoulder) but that is not what I want. I want the elbow to rotate in place (basically around it’s own coordinates)
I tried
Every node rotates about its origin–the (0, 0, 0) point of the node. If you want the arm to rotate about its shoulder, it’s up to you to arrange it so that its shoulder is at the (0, 0, 0) point.
Since you didn’t create the model, that’s a little bit harder. But you can do this by introducing a dummy node. Say you figure out that the point inside that shoulder that you want the elbow to rotate around happens to be the point (1.2, 0.5, 3.5). The trick is to create a new node for which that point is (0, 0, 0):
