I’m using Ragdoll 2026.7.21 with Maya 2026.
I’m creating a 600-frame animation at 30 FPS. Every time I use Ragdoll, I’ve noticed that motion noise starts to occur around the 500-frame mark.
No matter which animation I use, noise always occurs around the 500-frame mark. What could be causing this?
Motion noise will always occur, even when the body’s “Behaviour” is set to “animation.”
The video might be a little hard to follow.
I’m creating 600 frames using a looped animation of the same movement. I noticed that the torso was wobbling around the 500-frame mark.
These are the settings I configured.
Hi @Tetsuya_Hida , welcome to the forum 
Thanks for those videos! Quick question, was that happening after “Record Simulation”? If so, can you screenshot your simulation record settings? Or it just starts wobbling after marker assigned?
Thank you for your reply.
This issue has been occurring even before I run “Record Simulation” I’ve also attached a screenshot of the settings screen.
That sounds strange. Because markers should have no effect to the rig before recording. 
Is it possible to share the scene with us? By upload to the forum here, or email to us. If not, what about a minimum reproducible? Like, remove everything else (things that are not shareable), and only keep the spine joints and markers, with a simple up-down animation, no mesh.
Yes. This is the scene file.
Thanks @Tetsuya_Hida , that scene file helps a lot.
I found that glitch was actually from record simulation. As you can see from my screenshot below, the wobbling you were seeing is coming from rSolverLayer. With recording option “Include Kinematic Keys” enabled.
Try delete rSolverLayer, and re-record the simulation with “Include Kinematic Keys” unchecked, the wobbling should be gone.
But this indeed is a bug, so I will keep looking into it. In the mean time, see if uncheck “Include Kinematic Keys” works for you.
Sorry, you are right @Tetsuya_Hida. The glitch happened before simulation recording. In my recording below, I have rSolverLayer deleted and at frame 123, it is clear that all the markers suddenly stopped.
Thank you for checking the animation issue.
When I unchecked “Include Kinematic Keys” and recorded the animation, the torso no longer shook, but it appeared that the arms were still shaking.
Hi @Tetsuya_Hida , we made a new released 2026.07.30, please give it a try 
Thank you very much!
I tried the revised version and didn’t encounter any problems.
Thank you for your prompt response.
