Custom Skinny Boned Mesh Rig Freezing Randomly

Hello everybody! I’m currently working on a custom rig using a skinny boned mesh for my Roblox project. It’s meant for really smooth, fluid movements of characters, but occasionally, it freezes up completely at random times during gameplay. It’s been long enough that I’ve spent troubleshooting this problem and still can’t seem to find where the freezing is coming from. Hopefully, someone in this thread will be able to post some insight or suggestions on how to fix this issue.

  • What are you attempting to achieve? (Keep it simple and clear)

Currently, I am working on a custom rig with a skinny boned mesh that should move smoothly without freezing or getting stuck at any point.
The rig functions as a morph that players can turn into, and it uses a humanoid for animations.

  • What is the issue? (Keep it simple and clear - Include screenshots/videos/GIFs if possible)

It sometimes freezes while in use, for no apparent reason. There were no errors in the output; it sometimes would just stick. The problem comes up randomly and affects movements in the rig.
This issue appears randomly and affects the rig’s ability to move, especially after scaling the character beyond 3.25, it is just stuck indefinitely when the scaling value is above that.



  • What solutions have you tried so far? (Have you searched for solutions through the Roblox Wiki yet?)

I set all the collisions of the parts to off.
Added ‘Massless’ to all the parts of the rig.
Looked through relevant solutions on Roblox Developer Hub and Wiki.
So far, no patch has worked; the rig still freezes from time to time.
