hi there, i wonder if anyone can help me. i am currently working on an animation that involves dynamics. i have set up a simple particle cloud which is built up of 12 blobby particles, the threshold has been upped to give a blobby look and a newton field attached to it. i want geometry icons to push through the surface of the blobby as if they were streching the surface before they brake through it. has anyone got any sujestions as to how i might go about the surface stretch part.
