Path Deform/IK control creating little twists.
show user profile  BishBashRoss2
Hi! Got a snake model that I need in various poses, currently set up with a spline IK control. This seems fine for making it wriggle along but if you try to coil it a little it gets these little twists in it. The same thing happens when I use path deform.

Is there an easier way for me to go about posing the snake, currently I am moving each bone individually and there are lots of bones. Getting quite stressed!

You could try using an actual spline itself as a bone, you can then bend it about using the verts. The only problem is it doen't keep the length fixed as you can stretch it but it might solve the twisting problem

Ah the ole twisting bones in IK, I've got to give credit to biped for doing this automatically as it's not easy to do manually. I do remember a time when I learnt how to do it while trying my hand at the auto-clavicle... however, if I had to do it again now I'd probably just stick with FK and use wire paramaters to say "when I rotate this 100%, rotate that other one by 50%"

Animating will require a little more effort, but it's all the same when you boil it down to the basics of pose to pose.

Uh, Dave I think you're thinking of twist links.
