Hi all, i'm new to houdini and i'm missing here…. ops: , a cloth object (grid) with 4 pin constraints, one on each corner, a sphere falls on it, but my cloth object does not influence the ball, it just keep falling stretching the grid all along… i'm crazy looking for it but none of the RB or Cloth properties seems to solve this, i'm really missing something probably quite simple here…. anyone please…? :roll:
