3ds Max - Bake/Collapse an animation with IK?
polycounter lvl 19
Hey all,
So I've made a simple animation for my game project but I added in IK solvers just to make it easier to animate the sequence because I thought you could easily just bake/collapse the animation to every frame and then delete the IK and the animation would remain intact. However, using the Motion Paths collapse function, when I delete the IK, the legs immediately fall through the ground and the entire animation is ruined. I also tried simply exporting an FBX with a key for every frame, and not selecting the IK rig when exporting, but this too broke the animation.
How do you bake out the animations and remove an IK rig so the animation isn't ruined?

Baking out to FBX should do it. Make sure you start from the original animation, not the one where you tried to bake it. Make sure to learn the exporter bake settings; https://help.autodesk.com/view/3DSMAX/2022/ENU/?guid=GUID-31EA2A4F-A126-498B-96E8-31811522738A
Sorry, I'm a little confused by "Make sure you start from the original animation". So what I did was rigged the character, then exported to UE4. Then when working on a particular animation, I added some IK Solvers to help assist, but when I export an FBX, if I leave the IK in, UE4 says the skeleton is incompatible because there have been changes. If I don't include them, then the feet drop through the floor. I wasn't ever intending the rig to include the IK as I don't need it in the game. There was no original animation. I will take a look at the link though, thank you.
Collapse controllers should do it. I forget where the button is
What Eric said should work though provided you're exporting the right objects
Thanks poopipe. I'll look into it :)
