[SOLVED] Softbody mesh working weird when attached to chain (obi rope)

[eduardoseitz]

These only show the settings for the topmost rope, but there's 5 ropes in total? Or are the 4 lower ropes part of the softbody?
In case there's only one rope, it looks fine for me: the lower control point should be set to not collide with the softbody (setting it to collide with nothing is one way to achieve it).


Looks like the mass of the softbody is really high compared to that of the rope(s). Large mass ratios require more substeps to bee solved accurately - like in all physics engines-. An insufficient solver budget will result in spurious compliance (fancy word for unwanted elasticity).

Either use more substeps, reduce the mass of the softbody, or increase the mass of the ropes.

kind regards,

There is only one rope (the top one) the bottom ones are fakes that look like chains but they are actually part of the punching bag mesh.
The collision is setup right like you commented so I don't know what that spinning bug is, do you think it might be the solver? (screenshots https://drive.google.com/drive/folders/1...IV35vYJiSe)
The second bug I fixed by increasing the mass of the rope. Thank you.
