As a follow-up, if you use the vex solution to modify their transform intrisic it also works, but with the same problem as before...the geometry is changed from the SOP Solver, but the collision keeps on using the original size :p this is starting to be harder than I thought... regards,Javier Mero?o > From: javiermerono at hotmail.com > To: sidefx-houdini-list at sidefx.com > Date: Fri, 6 May 2016 11:30:07 +0200 > Subject: Re: [Sidefx-houdini-list] Rescaling Packed primitive in DOP > > I tihnk pscale has nothing to do with how pieces are simmed.
