Articulated Joint/Turntable/Bellows

Hello! I’m currently working on an articulated bus joint, and I’ve been running into a few issues.
The bellows creating this V shape and shift either left or right depending on which way the bus is turning, and is demonstrated by the images attached.

The bellows itself are weight painted and deformed using bones, but I’m generally just having issues with the turn table itself. In general, the physics seem right and the turntable IS centered with both halves of the bus, however the issues mentioned remain present.


This first image, it shows the right side of the bus shifting towards the left.
The second image does the opposite.

Anyone who has experience with rigging buses and/or accordions, let me know what you suggest I should do please.

You can also see the shifting occuring within the transparent bellows on the inner turn side.

How did you made the mesh bellow to work? I’ve triying to do that but still havent figured out how to deform without animations!

I’ve done it using CFrame! :smiley:
It’s the standard nowadays for vehicles and anything real-time.

How did you weighted the model? I just cant get the perfect weight and it will just move rare :sweat:

Nvm, finally got it, and im in love with ittttt!
It also happens to me the thing in ur pics above btw
