Recording destroys animation, cache looks fine

[Mary_Peters]

Hey everyone.
I am trying to simulate the muscles for my leopard animation with ragdoll like Nav showed in his tutorial. In the preview it looks great, but once I press record, it completely messes up my animation and seems to move everything to a single point in space.

I have already moved the start frame from 1001 to frame 1 and I am not sure what is happening. It would be great to hear if anyone knows what is going on.

Take a look:

And thanks so much in advance

Heya @Mary_Peters and welcome to the forums!

To debug recording-related issues, try Extract Simulation.

Problem with recording simulation

Ok, let’s try and perform each step of the recording one at a time, to find where things start to misalign. Instead of Record Simulation, run Ragdoll → Utilities → Extract Simulation You’ll find an animated joint hierarchy where the simulation is, this is what Ragdoll exports from the simulation before then constraining your controls to it and baking the constraints to keyframes. You can try and manually constrain one or more controls to these joints, to see whether your controls are able to…

It’ll help identify whether the simulation is coming out alright, and whether the problem lies with attaching the controls to it afterwards. Which you can also test manually - by constraining your controls to the extracted simulation - or automatically.

Likely that the controls you are recording onto can’t be animated like you’d expect, in this case I would expect the translate and rotate channels to all be unlocked, for example.

Give that a go, and let us know what you find.
