Hi,

Instead of calculating a spring force, fix the particle (by setting its inverse mass and velocity to zero) and set the particle position directly. That will completely get rid of the "spring thing":


Note that you should revert the inverse mass to whatever it was when you want the particle to start behaving normally again.

Thank you, it works.
