Kawaii physics does not work with control rig.

[endyrare]

Hello i love kawaii physics and i would love to use it in my animations. But im having an issue with using kawaii physics in conjunction with control rig. upon adding the anim class blueprint to the skeletal mesh i get this crash:

Is kawaii physics not compatible with control rig? Is there any workaround? Using UE 5.02

Hi, sorry for my late reply...
Hmm, I have tried to repro this issue, but I can't found any crash.
Would you please how to repro it?

thanks

Hello! Thank you so much for replying! I would absolutely LOVE if i can use kawaii physics in conjunction with control rig, but as you already know it crashes. Ill be sending you a video reproducing the crash as soon as possible. I really appreciate that you got back to me! ~Andy

Hello, here's a gif reproducing it. https://gyazo.com/fdba52f0a95f0dd235658cc248c0bc80 it happens when you have the animation blueprint selected and you add in the control rig asset through the level sequence.

I've faced this problem too @pafuhana1213 when I was dealing with the exact same thing. This was instantaneously happening after adding a control to something that had kawaiiphysics, compiling the Ctrl Rig and trying to run it in sequencer. It completely kills the engine as long as it has any control rig attached to something that has kawaii.

Try to apply a Distribute rotation node into a skirt with kawaii, it might reproduce the bug.

I hope this information helps. Merry Christmas!

I've been facing similar problem.

Have you ever tried to compile the ABP (or post-process ABP on the mesh) which is causing the trouble? I'm pretty sure that the compiling causes the same crash.

If you put Kawaii-Physics node(s) in an animation layer in the ABP, that's the cause of the crash. You don't face the same problem in UE 5.0.3

Solution is quite simple.

Delete

InitializeBoneReferences(RequiredBones);

in FAnimNode_KawaiiPhysics::Initialize_AnyThread()

Or if you're not a programmer,

GET KAWAII nodes out of the animation layer. Place them in the main anim graph

For the record, AnimNode_AnimDynamics has the same problem.

Hi guys,

I haven't been able to reproduce this issue yet, but I think the method suggested by @Heeju-Kim-Bloodlust is great, so I committed it.

If it happens again, please reopen this thread. Also, it would be great if you could provide detailed steps to reproduce.
Thanks!

Hi,

I'm not a professional, and not really good with code. I have the last version of the plugin, but I still have the crash when I trie to use it with a control rig. Have you a solution or have I missed something?

Thanks!
