I have tried this several times now and always come up with the same results. By the time I get to 11:14 my joints do not react as Emma’s do in the 22-2-Twistable_segments.mb file. When I translate my leftUpperArm_end_bind_JNT across the Z axes the chain is broken and I have a leftover leftForeArm_start_bind_JNT. What exactly is connecting the upper arm and forearm joint chains at the elbow?
Translating Emma’s leftUpperArm_end_bind_JNT accross the Z axes the chain stays intact.
