  1. Pop grains wokflow question

    Hello everyone . i have a question that about pop grains . In houdini I'm used upres sand tool(pointreplicate).but is looks like unreal. So how to realize best point interpolation? Just use pointreplicate or another ways?Thank you very much...
  2. Is it possible to control the "surface stiffness" of a granular sheet, so it will act like a sheet of paper or another stiff material?
  3. POP Grains - Experiments and Issues!

    Hello, I have been experimenting with Grains node and shelf setups as as custom setups. I started with a sphere, then a sand castle and last was a statue. Some results were pleasant then I ran into some issues. Weird and strange behaviors such as floating sand clumps. Mainly it looks like too much force or friction. The problem that the solver feels like it is too sensitive (minor values can change things very quickly). Any pointers or advice is greatly appreciated.

  4. I have an RBD Voronoi fractured object that falls to the floor, and each primitive group is given an impact time attribute when each piece hits the floor. The system works so far - I import my fractured object, delete all the primitive groups except for one, and select the Voronoi object that will turn into grains at the moment of impact using a switch that changes the input from the primitive group to the grains. As long as I'm working on a single primitive group, it works. Here's a GIF showing the result on one group. Question: How do I use my effect - that isolates a primitive group and turns it into grains at a specific frame - onto multiple primitive groups within a foreach node? My attempt at a solution: With my system in a for each subnetwork, I replaced the group name that was previously fracturepeice_15 to 'chs("../each1/group")' to reference the current group that is being processed. However, the final result of the ForEach shows only one primitive group being turned into grains or the entire sphere that was fractured being turned into a clump of grains. If anyone can shed any insight on what to try, would be very grateful. Voronoi-ODFORCE.hipnc
