David, Have you been gone for awhile? If so, welcome back. I don't know if you ever resolved your Bones troubles, but I just posted some new info that might give you some more ideas. I can't believe we haven't caught it yet somewhere. Did you ever have any problems getting bones to work with simple hierarchical movement, or just the Inverse Kinematics? Could it be that you did not lock down your object's main axis, and that's why the skeleton seemed to separate from the mesh when using IK? You may need a principal bone grouped as the first child to your mesh, with the whole geometry selected as its Big and Small Bone Subgroups, to anchor the basic geometry while you move the limbs. When using IK, the mesh object (master parent) and this first anchor bone may need to have their POSITION and ALIGNMENT freezed. Have you tried something like this? -Tim

Hi Tim, I haven't been gone really, just doing something else than computers. 🙂 First time I had this trouble was when I boned a dino. I made some mistakes and thought that they caused the trouble. So I started from scratch again avaoiding all the mistakes, but exactly the same problem. I tried a different object (the cow), but the same again. After a time I tried again, but again this trouble. It's some time ago now and I haven't done any complex bones objects since then. So I'm a kind of able to reproduce the problem or maybe I'm only able to reproduce my own mistake all the time without noticing it. The funny thing is that it only happens when I use IK, not when I forward kinematics (the good old way). BUT I haven't tried it with 3.2. Maybe something has changed since 3.0 and it's solved now. >> Did you ever have any problems getting bones to work with simple >> hierarchical movement, or just the Inverse Kinematics? No, I have boned many objects and didn't have trouble. -David PS: you never looked at my banana animations, did you? PPS: I think I have just found a solution. I'm not 100% sure if I found the right thing but at least I'm now able to use IK with the dino the way I want. 🙂 No, I'm not going to do another dino animation. There are already too many dinos and I can't see them any more. <g>
