Resilient Picture Company shows how you can make an explosion with trails using sparse solvers.

Check out this tutorial series from Krishna Bala (Resilient Picture Company) that shows how to work with the sparse solver in Side FX Houdini to create an incredible looking explosion with trails. The sparse solver or the pyro solver in Houdini creates a sparse pyro simulation on any given object and is used to create both fire and smoke.

Make sure to check out the last tutorial in the series, which covers some of the new sparse solver updates in Houdini 18.5.
