Flickering in Flip Simulation Jan. 22, 2026, 1:22 a.m.
This has worked for me before https://www.youtube.com/watch?v=oSotagH9K0g [www.youtube.com]
Anyone else notice H21 pyro viewport rendering issues? Nov. 27, 2025, 3:24 a.m.
I hoped this was just a fluke in one of my files but it's a constant issue for me - if I sim pyro I constantly get issues where my pyro volume just disappears while I click through the timeline. Oddly, if I quickly scrub the timeline and release, pyro renders, which makes me think this is just a bug with H21 - in this video I was trying to show colleagues the differences between attribs but this bug makes it kind of sad/hard to illustrate
(video attached, looks like video upload didn't work)
I've got an amd rx7900xtx (4090 equivalent) and like 7k$ worth of other computer components
Has anyone else noticed this issue?
Also, does anyone know where/how I can submit a bug report?

Houdini 21 pyro + lighting viewport issues? Nov. 13, 2025, 1:37 a.m.
Added a skylight to my scene and now my viewport and MPlay look like this

Smoke seems to stop rendering properly if I add any light to the scene
I have an rx 7900xtx, anyone else have this issue/know of a fix?
