Setting up pyro sim right

Recommended Posts

Hello all,

I am a beginner at Houdini, but I try to understand some VEX coding, some easy coding to give velocity to normals. Now I am trying to achieve a Explosion with trails.

I have set up a particle system where I have given some velocity to the particles. Now I am trying to use this particle system to drive the smoke/explosion simulation. But I don't know how to set it up right.  
Because I have tried the shelf tool "Explosion" and "fireball" but the result looks not so good. The smoke on the particles are dots. I have tried to increase the substeps in the pyro solver but nothing has changed at all.

is there a right way, probably I do it wrong in some way.

I am provide my Hip file here, in the case if someone knows how to do it It would be very thankfull.

You can improve that by making the volume source more interesting (noise) and playing with forces. For manipulating the vel field the "Volume Velocity" sop is a quick solution.


If everything looks way too blocky, disable your scene view's display options/ textures/ limit 3d textures setting.
