Is there a way to freeze transformations on a bone? My use case: My character rig’s rest pose does not match up with rest pose of the input animation. I want to rotate my rigs rest pose around the it’s Y axis to line up with the rest pose of the input data. I tried passing a local matrix with th…

Hey! do you mind reproducing the question in the Playground? there are some options (like forcing a call to return to rest, or cancelling animations but it will be easier with a repro)

[Screenshot 2020-09-10 at 17.36.59] @Deltakosh here’s a Playground that shows what I’m trying to do. It works, but it ain’t pretty. The only way I managed to get the desired result was by copying my skeleton and modifying it in steps. Gray (srcSkeleton): Input data Gray (rigSkeleton): This is t…

pinging @Cedric and @Evgeni_Popov for help :slight_smile:

@Evgeni_Popov that’s easy! Check out this one . The interesting lines are hips.rotationQuaternion = new BABYLON.Quaternion.FromEulerAngles(0, Math.PI, 0); // Freze somehow? //hips.freezeTransformations(); // If frozen correctly, this should not reset the skeleton. hips.rotationQuaternion.set(0, …

mySkel.bones.forEach(b=>{ b.setRestPose(b.getLocalMatrix()) }) https://www.babylonjs-playground.com/#308TR3#1 We had a argument for this on the SkeletonViewer updates at one point but that was not the correct place for it to live. Maybe need to add a method on the skeleton class that is skeleto…

[image] Pryme8: Maybe need to add a method on the skeleton class that is skeleton.setCurrentPoseAsRest(), or something like that? That seems nice to have to me.

Added it, will be pushing in after my dumb long build process… We have it for the whole skeleton and also per bone now. Add setCurrentPoseAsRest BabylonJS:master ← Pryme8:Add/Skeleton/setCurrentPoseAsRest opened 06:50PM…

Thanks @Pryme8 . It’s just that hips.setRestPose(hips.getLocalMatrix()) doesn’t really work. Or perhaps I’m just confused since mySkel.returnToRest() does not assume the new rest pose, but instead reverts to the original pose. Is it a bug?

I’m working on it, but I’ve run into an other issue while doing it.
