Re: dual quaternion enveloping
+1 about what Enrique said about the flipping with 180 degree movement. I would highly recommend using a weight map to blend between dual quaternion and linear to address problem areas such a the fingers...they trend to get funky when poised into a fist.

Re: dual quaternion enveloping
Thanks for the info guys. I won't be moving the model null around (heresy!) and mostly envelope to nulls rather than bones, so will give it a shot. Good to hear its being used in production.

Re: dual quaternion enveloping
ive used it many times in production, i had no issues with it. just blend between dual quat and linear with an envelope and you should get some really nice deformation it flips when you rotate something past 180 though, so dont use it if your character is especially twisty On Wed, Oct 29, 2014 at 3:22 AM, Grahame Fuller wrote: > Scaling should be OK, but don't touch bone lengths. > > gray > > From: softimage-boun...@listproc.autodesk.com [mailto: > softimage-boun...@listproc.autodesk.com] On Behalf Of Alan Fregtman > Sent: Tuesday, October 28, 2014 1:42 PM > To: softimage@listproc.autodesk.com > Subject: Re: dual quaternion enveloping > > I seem to remember weirdness if dragging the model null around. > On Tue Oct 28 2014 at 11:02:25 AM Matt Morris matt...@gmail.com>> wrote: > Hi chaps, > > I'm very tempted to use this on some characters here, I read that it does > now support scaling, are there any remaining caveats still out there to be > aware of? > > Cheers, > Matt > > > -- > www.matinai.com<http://www.matinai.com> >

I seem to remember weirdness if dragging the model null around.

dual quaternion enveloping
Hi chaps, I'm very tempted to use this on some characters here, I read that it does now support scaling, are there any remaining caveats still out there to be aware of? Cheers, Matt -- www.matinai.com
