  1. voronoi fracture, how to avoid straight segments

    hey @toadstorm, your article about texturing flowing liquids saved my life once! Thx by that
  2. voronoi fracture, how to avoid straight segments

    Yeap haha I did an example. Have a look at the file, it works pretty fine with the convex collision shape RBD Boolean Fracture.hiplc
  3. voronoi fracture, how to avoid straight segments

    Nope, I mean convex shapes. I know it looks weird and the simulation shouldn't look right but, if you have a lot of pieces it's impossible to notice it has a "wrong" collision shape. Concave is too expensive on calculation and do cause a lot of problems. In this situation, with just a few pieces, you could break each piece into smaller ones to have a better collision shape. You know what I mean? Then you can glue the smaller pieces together to form the big piece with a better (but not perfect) shape.
  4. voronoi fracture, how to avoid straight segments

    I always simulate with convex collision shapes and most of the time you can't see the diference at the final sim. I think it totally worth it
  5. voronoi fracture, how to avoid straight segments

    Hey Nicola, like Kiryha said, go by boolean. You will have the perfect control over those shapes. Voronoi fracture is an old technique, imo. It's still good in some situations but not at all for other ones. There's this awesome tutorials by steven knipping:
  6. Create multiple FEM over time?

    Hahahaha, the file is awesome enough I hope this post stays here forever
  7. Flip Fluids with Color

    That's super cool! I think it would be better to do it with pyro, at least in this situation the simulation looks more like smoke than liquido Anyway, if you want to color flip you can apply the color on the emitter points (the flip particles should keep this attribute) and then transfer from the flip particles to the mesh. You'd need a very dense mesh though
  8. Do FEM solids bounce ?

    Hard to say, can you publish a preview of how your scene looks like?
  9. Do FEM solids bounce ?

    Hey Antoine, try changing the Integrator Type to ABE2 in the Finite Element Solver not sure if it works on all situations but once it worked perfectly for me
  10. noise on internal faces of a shattered geo

    this! You can get some incredibly cool internal detail with it
  11. Constraint RBD to Cloth (or Grains)

    Hello guys, How can I attach a rigid body object to a piece of cloth? I'm a bit lost on this. I tried cloth and also pbd with no success, now I have no idea on what i should try. There's a file attached (using grains). It's a starting point if anyone can give it a try. Cheers - Alvaro rbd.to.grains.v1a.hiplc
  12. noise on internal faces of a shattered geo

    Hey Nicola, the voronoi fracture node have some good options for it. It doesn't create jagged edges between the inside and outside faces though There's also a tutorial from Simon Fiedler explaining a cool technique for achieving the interior detail with jagged edges. It's not 100% perfect but it works in a lot of scenarios. But nowadays you should totally use the boolean fracture techiques, it's way better than voronoi
  13. Granular Sheet - Moving Pin Constraints

  14. Granular Sheet - Moving Pin Constraints

    Good! Is it working now? You just have to use an attribute copy inside the sop solver to update the targetP data
  15. Grains cloth - bend resistance

    Hey Michael, not sure if it will fit for what you need but I've noticed that if you increase the simulation steps the object gets stiffer. The more you increase the harder it looks
