emix941 Posted June 13, 2020 Share Posted June 13, 2020 Hey there! I'm quite new in Houdini. I do not really like to ask questions, I rather tend to find answers by myself. But sometimes I hit the wall. This is the case I need your help guys. Im trying to make RBD sim in DOP NET with the simple spheres. My goal is to have variable scale and color of a sphere according to the noise. I manage to get color with POINT VOP in SOP SOLVER with MULTI SOLVER. But I stuck with the scale of a spheres. They inherit pscale from a GEO level. I would like to use pscale in DOP NET and manipulate it with the POINT VOP. Any ideas how to achieve it? I tried to make it with the particles, like in this tutorial https://www.youtube.com/watch?v=qXoSEnh94YQ&t=246s But particles tend to move erratically and not act like proper RBD.

dleonhardt Posted June 13, 2020 Share Posted June 13, 2020 Hey Emix, the only way I know of to scale geometry inside a RBD sim, is to modify their "transform" intrinsic and have Bullet recalculate the collision geometry per frame.

emix941 Posted June 15, 2020 Author Share Posted June 15, 2020 Thank you so much Dennis! I hoped that there will be less mathematical approach. But oh well. I have one more question for you. Maybe you know any way how to restrict object to move only in given plane during the sim. For example only in xz and not in xyz? Quote Link to comment Share on other sites More sharing options...
