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?

Wondering how to actually simulate thrust? July 18, 2025, 12:39 p.m.
Image explains it pretty well, I'm wondering what the best way would be to create something like this. Another example would be a fire-hose that's not being held at one end and ejecting water at a super high velocity - imagine how the hose would be flopping around like crazy, connected at one end and free to move on the other. Is something like possible using dynamics or some other method? I'm interested in being able to create these sorts of complicated animations without needing to key frame any bones/avoid traditional animation/would like a realistic solution for the problem
