Extreme stepping on sparse pyro sim Jan. 20, 2026, 6:08 p.m.

Here's an image showing the particle emission to generate velocity, and the resulting fire sim.

Extreme stepping on sparse pyro sim Jan. 20, 2026, 6:07 p.m.

I have a problem with a sparse pyro simulation. I'm trying to use this method (https://www.youtube.com/watch?v=ui43YK0cnXE) to eliminate stepping in the sim, but even when using the velocity (or I think it's using vel)of the emitted particles, I still get extreme stepping. Here's a sample hip using a free hda here: https://www.patreon.com/posts/velocity-blur-88100621 [www.patreon.com]

Thanks for any help.

Console Warning message June 4, 2022, 1:06 a.m.

Yes, I'm getting this when I hit save (Ctrl+s).
Warning: There is no hotkey for h.pane.gview.state.sop.brush.orient

Couldn't find any specific reference to this in the hotkey editor. Houdini 19.0.622

Edit: It also happens when I hit the hotkey to rewind to the first frame, and when the viewport is in focus (or mouse is over the scene view).
