Hello!
I am back using ragdoll again!
Maya 2022.5.1
ragdoll 2023.12.13
I have created a biped rag and exported.
when import to a new scene. The thigh kinda split open. 
I tried to fiddle with the geometry of the mesh, or use capsule but it still end up splitting in new scene.
Hola! Would it be possible to show what you see, and if possible provide a series of steps on how we can reproduce it here? Either by uploading what you have, or starting from a blank Maya scene.
unfortunately, I can’t upload the screenshot.
I have used the dude geometry. The rigging process seems okay to me. But only when import to new scene, it does not work as how it is rigged at default.
Without seeing what you are seeing, and without being able to reproduce it on our machines, it’s unclear what we can do. 
If you manage to reproduce it, do let us know.
Also bear in mind we do not support versions other than the currently released version, which at the time of this writing is 2024.07.01.
I see. not sure about re producing. its just the .rag file does not behave the same as how it was set up on a different maya file. Since the version is no longer supported. I will go see what I can do.
