Converting IK animation in 2.55

Jakten_hizeme · Apr 2011

Hi, I am attempting to import a character into a game engine that has IK legs. The problem is when I import it the legs don't move. I need to find a way to bake or convert the IK poses to be FK so I can remove the IK information. Does any one know if this is this possible at all?

Typically you have some kind of FK rig that snaps to your IK chains. The FK rig is what you export. But it all depends on the software and engine you're using.

This is one of the reasons 3dsmax/Biped is so popular it handles all of the IK/FK on the same pieces you export. With CAT or Maya you end up doing a lot of technical heavy lifting...

Hmm shit... this might be a much bigger problem than I thought then. I guess I can try to add FK bones though I doubt I can since it's already bound and animated.

Thanks for the help.

Normally you work out your rig and exporting before really digging into the animation... which software package are you using.

I'm using Blender 2.55, sorry I should have put that in the title.

Has anyone got any pointers even that might lead me in the right direction?

What game engine are you using? Many exporters have a function that sample the animations per frame. This negates the need to bake out the animation.

It was entirely made by our programmer so maybe when I said game engine I probably should have just said game. We are exporting from blender into Collada files though.
