Pancho Posted October 19, 2018 Share Posted October 19, 2018 I checked the docs, but unfortunately couldn't find anything yet. I wonder how to constrain grains together to achieve some mud/soil like behaviour (clumping) with vellum. Vellum creates the GEO and CON output, so how do I create the constraints? I managed to create attractionweight and -stiffness attributes on the grain particles (before GEO output) in order to come up with different behaviour, but these aren't enough to produce proper clumps. Cheers Tom P.S.: If I transform (move) the GEO output, do I also need to move to CON output? Quote Link to comment Share on other sites More sharing options...
nailqq Posted October 20, 2018 Share Posted October 20, 2018 Hi man. Check the file, may be it will help to you. Also you can use clusterpoints node on your grains and activate clusterattrib checkbox in vellumconstraints node for clustering.

Pancho Posted October 20, 2018 Author Share Posted October 20, 2018 Ah, finally managed to do it. After the grain_constraints node you need the vellum_constrains node with target_group_type set to points and constraint_type set to glue.

Harper Posted November 2, 2020 Share Posted November 2, 2020 Hello, I gave the scrip a test and it just explodes upon first frame of the sim. Has Houdini changed something about how this works in 18.5? Quote Link to comment Share on other sites More sharing options...
