Re: RE: xsi 6.x and envelopes ( severe issue)

[Adam Sale <adamsale(at)shaw.ca>]

the popping happens with default chain behavior. IK blend at one, Its not the IK chain being manipulated that pops.

 

Lets say I'm moving an IK box for a hand, or rotating a bone in the forearm. It works fine, then lets say I go and adjust a finger bone angle on the same arm. I may be able to adjust a finger or two, but then inexplicably, the other bones in different chains will pop, or the wrist angle will pop to a new angle...

 

I've built and animated a lot of characters in XSI over the years, and haven't come across this before.

 

I have Monday free Manny, can I give you a buzz then?.. hopefully we'll get a scenario where the popping actually occurs.

 

Adam
