Default Keyframing Dynamics - 11.09.2018, 01:41

I know how to keyframe bone animations, transform animations in C3D.

Is it possible to keyframe models using the physics engine (dynamics) like the example like Rigid_Body_Spiral.jas?

I've tried all the usual key framing steps I do with bone animations... nothing seems to work.

I can see how you can bake a simulation. But is that only for baking animation. Any help here would be great... as I can't find any useful pointers on this one.

Im under the impression you need that for your USDZ file format experiments - but the advantage of physics is that you dont need keyframes after adding dynamic tags to the objects. Just recording via baking is possible as you already found out - files size increases dramatically BTW.
(Theres a script herein the forum to export obj-sequences if I recall correctly - not sure if this will help though with your project)

Hi Frank,

Yeah, Im still doing my experiments with usdz! Having a physics engine like in C3D could help to make more complex key frame animations which use physics like object collision. Im exporting to either fbx or collada from C3D, which I then need to convert to gltF 2.0 (without embedded 64 base). From there I can create usda or usdz.

I played around with dynamics a lot today, and Im now assuming the feature is for mp3 animation sequences.
