I’m trying to get a curved geo rigged with an IK spline (every tutorial I’ve found uses a perfectly straight chain where this isn’t a problem), and the main issue is simply that once the curve is applied to the bones, they shift position, even when I haven’t touched the curve.
To my understanding it is simply because the bones must follow the curve exactly. This would be fine, however once the mesh gets skinned to the bones, it moves with it, they get skinned to where the bones originally was placed and then the geo gets nudged into the new position.
One (and so far the only) “solution” I’ve found is to have one curve point snapped to each bone, but that kind of defeats the purpose of having an IK as you normally tend to/want to have fewer control points controlling a more dense chain of bones, you also wouldn’t be able to take advantage of the handle control.
So what would be the best procedure if you want to keep the shape of the model? Maybe I just haven’t found the “maintain offset” checkbox or something.
Because otherwise I can only think of one options to fix this (and it sounds very wrong in my head) which is to create chain of bones, attach it to the curve, in pose mode snap the cursor to a bone, then in edit mode snap a new bone to the cursor (so it won’t get offset once the curve is in charge) and then just rinse and repeat for as many bones as you have and then delete the first chain of bones.
But that cant be right… right?
