[solved] ik:8 & z-axis.

[JossuaDC]

try to add the zwidth in the first frame as well.

First frame?
What first frame?

They're both the same, except for the second having a non-functional zwidth: tag.

Edit: The move itself is working perfectly. It's flawless. No bugs. The only problem I have is that the zwidth: tag doesn't function in an ik:8 (whilst the majority of posters here seem to think I'm delusional).
