ICE Prevent feet sliding tool
Posted: 02 Feb 2015, 12:06
Hi,
I am trying to build a small tool with ICE, to automatically detect the frames each foot needs to be pinned to the floor, and keep it from sliding (when you have a sloppy animation of a walk cycle for example)
Currently I managed to do a Boolean On\Off position constraint, it works pretty nice, but it has many limitations, and I've only tested it on a couple of animations on a GEAR Rig. (the foot controller needs to be on local zero Y to be detected)
What I wish to achieve next, is the ability to blend out the constraint over a pre determined span of frames (3 or 4 at the moment), and not have it cut off in one frame as it is happening now. This is where I currently hit a small wall I am not the greatest ICE "programmer", so if anyone has an idea, and cares to help, it would be great..
for path translation, I'll need to add foot orientation constraint as well, or somehow switch the rotation pivot of the foot to the front "toes" controller GEAR rigs has.. but that's later
You can download the 2015Sp1 scene and\or compounds that should work in earlier versions in the vimeo link.
Is it possible at all to blend the constraint over a number of frames within ICE?
I've played around with linear interpolation but for some reason could not get any result with it.. it just pops as a Boolean switch..
