Hey,
I have a dynamic chain of cubes that are connected by ball/socket connectors and springs - this chain dynamically follows a target object, like a tentacle.
I used the tracer to draw a spline through these cubes as a path for the Spline Wrap deformer to stretch a model of a tentacle across it, but when I use this deformer, the model banks and spins unnaturally upon sudden movement…
I tried fixing this problem by constraining cubes to the PSR of the original chain segments, locking their Up Vectors, then applying a protection tag to disregard all of the chain segment rotations and only allow XYZ movement - essentially I end up with the same chain, except the segments are locked facing upwards so when traced again the points aren’t full of rotation values… Still getting weird banking - even after using this as a rail spline too!
All I want, is to be able to use the Spline Wrap deformer and have the tentacle’s suckers facing upwards (towards the target object) the whole time without random twisting… I was thinking that maybe I should rig it with joints instead of the Spline Wrap Deformer… Would that keep the segments facing the right way up? I even set the Up Vector on the deformer settings - no luck!
Looked online and not found a solution. I’m sure it’s easy to do. Would love some advice on Spline Wrapping tracers without twisty artefacts!
