Great yeas that looks correct now eh? Good findings.
Sorry I was not working yesterday let me know if you still need a sample project though it looks like you have it sorted. EDIT: oh I see you’re in the UK.
(and I’d prefer not to send out my assets)
Good news then I just have one question, would you be able to tell me what curve type you are using for the spline and what is actually happening when a point gets rotated?
I would need to understand this to be able to use the spline Ik.
Cheers
