Thanks guys, I've made some modifications and so far (fingers crossed) it seems to be better. I did change all of my .getTranslation() and .setTranslation() (and scale, rotation) calls to .translation.set() or xform().
I also had been working on a tail rigging script, which had some interesting side effects - the tail had something like 35 joints in it and was rigged with a spline IK. Amazingly to me, as soon as I created the IK handle the framerate plummeted from running at about 40fps to 25fps. It was around this time that I started noticing the crashing, so I guess it makes sense that this could be the problem, though it seems very odd that a single spline IK would slow the system down that much. At any rate, I ditched half of the joints in the tail which halved the framerate drop and so far the rig hasn't crashed. I'm not 'simplifying' the curve that drives the IK, so perhaps having a ton of CVs on a spline IK system has some odd side-effects? I need to do some more research and testing, and I'll report back anything I find. I know this is the PYTHON in Maya forum, not the character-setup forum, but thought it might be of interest to folks. Anyways, thanks for the help guys! -JP On Wed, Apr 28, 2010 at 2:33 PM, shawnpatapoff <[email protected]>wrote: > We've had similar issues and basically had to turn sections of the rig > off to see what portion of the rig was crashing. > > On Apr 28, 1:46 pm, John Patrick <[email protected]> wrote: > > Hey all, > > > > Wanted to throw this out there to see if anyone had experienced something > > similar.
