Houdini custom Divergence Fields

RnD with Houdini & Krakatoa. I build custom divergence fields using Houdini Gas Microsolvers for better simulation control. Used these divergence fields to control the fluid sim. Then advected 30 mio particles within these fluids inside DOPs. After that did 10 different seed-caches, all being output with the Wedge-ROP. Re-imported these wedges and wrote them out as .prt files with the Prt-ROP by Michael Auerswald. Rendered all 300 mio particles with Krakatoa in C4D using the Kajiya-Kay shading model.
