phys.6dof.spring spring mass bug ?

    Jun 13 2018 | 3:26 pm
    Since pmpd and msd are deprecated, I'm trying to build a simple 2D spring mass model using 6dof. Moving an object around, and having a second object following the first but with mass-spring behaviour. Unfortunately, everytime I open the phys.6dof.spring example, it works for about 4 seconds, then the tore and sphere disapears. When i try a getposition on one of the jit.phys.body i get "position nan nan nan" from the right outlet.
    I get the same kind of magic disapearing with mat mat's spring patch. (from this topic : If i dont touch anything, it works like a charm, but if I click on the impulse message, 4 seconds later, everything is gone.
    The other phys examples work fine (even the 6dof help patch). OSX 10.9.5 Max 7.3.5
    Any idea ?

      unfortunately I can reproduce. This is the first I'm seeing this behavior and I'm not sure of what's to be done to fix. I'll have a poke around and see if I can come up with a workaround.
      thanks for the report.

      I managed to do my patch from scratch without triggering the mysterious bug... For those interested in reproducing PMPD or MSD behaviour :
