How to set vellum grain constraints?

Recommended Posts

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?

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.

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.
