Everytime I export any fire or smoke particles in a video they move rapidly fast in the new 2025.1.2 is there a work around? or will this bug be fixed soon?
Hi again, I find this happening with the material video as well, the video export speeds up the foptage, please fix soon.
hey welcome to the forums.
i think there’s an option to for as to where the particles get the time information from.
i don’t recall exactly but you can find them on google.
the time info when exporting movies is going to be different, so it looks as they speed up.
same for movies.
i don’t use twinmotion (which seems like is what you’re using), but in regular ue that’s using the movie render queue.
for videos i export the video as a png sequence. if you use a video the decoder decodes it in real time, where the export has much lower frame rate.
btw beware, you’ve posted in unreal engine category. this is the wrong category, you should post in “Twinmotion”. that’s where the experts on twinmotion are. a mod should be able to move your post, but i don’t know how to ask them.
I’ve got the same problem. A cosy fireplace turns into a intense blaze. I thought it might’ve been the FPS (Mine was set at 60) but changing that doesn’t make a difference. Seems like a bug to me 
@nande The fire particle object in Twinmotion doesn’t have any options unfortunately.
i haven’t used twinmotion, but i’ve used the media export and the time source is an issue there too. if you’re exporting a video i’m confident it’s the same issue.
this could help.
you wouldn’t put it on tick. but you need to find a way to call this.
in a sequencer sequence you can add an event track, that calls an event that does this.
but i bet there’s a way to tell niagara to use twinmotion time source instead.
i know in sequencer you can choose other time sources, you should try that.
if only maybe create a global sequence and add niagara there, and change the time source. maybe it helps.
