Amzing project! Love to see the creative methods you come up with. One recommendation for the grain emission area. Instead of using boolean to create the emission area for the grains you can use an interection anaylsis node and a polyfill, which is a little faster if you are working with complex geometries.

Thanks for the tutorial. I don't quite understand the static object node. First of all, is referening data from RBD solvers (or bullet solver) while we are working on a POP netweork. Then , assuming that this is not a problem, why use a volume collision when it seems that is creating a surface anyway? Why not choosing a normal surface collision in concave mode? I've been reading the documentation about this but I still don't get it, maybe thre is a better place to search info about this. Thanks again :)

Hey Juha! My reply somehow dissapeared so in brief here are the steps that might help 1. Up the substeps of the popsolver - min 2 max 4 2. Make the heightfield part thicker, i.e. move down the box that cuts off the bottom part 3. Make the bounding walls a bit more "into" the heightfield to ensure everything is closed 100% :) Hope this helps, if not, feel free to drop me you hip file in discord dm :)

I very much enjoyed this training, thanks. I was wondering what are parameters I should adjust inside DOP network to improve collision detection of grains? I still get some loose grains going trough terrain.
