bighop Posted May 2, 2008 Share Posted May 2, 2008 I'm trying to get a character to do a somersault and or a back flip. When I turn IK off everything seems to move for the somersault, but having the character return to IK on for walking does not seem to work. (legs fold) I'm using the shaggy character, and it does the same thing as my character that I rigged with the 2001 rig. Would the set up machine help with this? or Version 15? I'm on 13 now.

Hash Fellow robcat2075 Posted May 2, 2008 Hash Fellow Share Posted May 2, 2008 You can do a somersault with IK legs. you just need to be careful to animate the feet to follow along as the body flips. For a quick motion like a flip you may need to keyframe the feet on every frame. I did this with all IK legs gymnast.mov When I load the Shaggy form my Yeti CD I see that going from IK to FK is seamless, but when I switch back the IK feet want to go back to where ever they were last keyed, which is understandable. Simple solution... after you switch back to IK, re pose the feet to where you want them to be. If your Shaggy is rigged wrong then something else might be wrong, but if you got him off the V13 CD it should be the same as mine. here's PRJ with the V13 shaggy and two chors that have him switching between Ik and FK. ShaggyFlip.zip "Flip" has him flipping. scrub it in skeletal mode to see switch happening shaggyflip.mov (that's quick animation, not polished animation ) "FK to IK" has: 00:00 Shaggy posed in IK 00:07 switched to FK 00:15 body moved. His FK feet follow of course. 00:21 switch back to IK. His feet go back to last keyed position 01:01 feet manually moved forward into correct position. I could have done this back at 00:21 so they would never jump back. Quote Link to comment Share on other sites More sharing options...
bighop Posted May 2, 2008 Author Share Posted May 2, 2008 Thank you for the reply. This is very helpful. I've been going nuts with this. So it can be done, I just have to do more posing then I thought. I thought I was going to have to invest in the set up machine. I thought that was the solution to this. Thanks again!

Hash Fellow robcat2075 Posted May 2, 2008 Hash Fellow Share Posted May 2, 2008 The (free!) "Squetch" rig actually does have seamless IK FK switching both ways. Installing it is a bit involved however. Quote Link to comment Share on other sites More sharing options...
bighop Posted May 2, 2008 Author Share Posted May 2, 2008 I guess it's time to "UP" grade to V15. I just have a grasp of the 2001 rig...now onto another rig! Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted May 2, 2008 Hash Fellow Share Posted May 2, 2008 Squetch works in V13. Quote Link to comment Share on other sites More sharing options...
bighop Posted May 2, 2008 Author Share Posted May 2, 2008 Ok I tried this. I see that somehow I didn't rig my character correctly. The IK on and off work totally different. Any suggestions on how to correct leg constraints? Quote Link to comment Share on other sites More sharing options...
