When I try to render a png sequence from Movie Render Queue, everything looks great except for my particles (fountain). They play once, but then freeze for the duration of the render. In other words, they don’t seem to be looping. Anyone know how to fix this?
Same problem here with several particle systems, they just freeze in place.
same here, haven’t found an answer anywhere — seems to have started either with 4.26 or a recent NVIDIA driver update. Sometimes they work, sometimes they freeze in mid-air—haven’t determined the cause yet.
Seemingly if you restart the render closer to the point the particle is started, it works, you’ll just have to do multiple renders and edit it together since apparently the particle systems can fail if the render’s gone too long.
Also having the same problem on 4.26.2. Particle effects run fine for the first ~80frames or so, then they slow quickly and smoothly to a stop. On this thread somebody mentioned it’s a problem with the way MRQ does temporal AA, but I’m not experienced enough to know why this creates the problem:
I hope Epic or somebody can find a fix or workaround because this is a total roadblock for my project.
Changing Temporal Sample Count from 64 to 32 has fixed the problem for me, for now. I also gave the Engine Warmup Count 32 frames on the MRQ AA tab which gives particles time to get going.
Thanks everyone. Andrea I will be sure to give that a try. Thanks for taking the time to track the solution down and post it here!
I found a fix. The same thing happened to me. Particles would freeze during a render, though they would play fine in the sequence. I tried unchecking Auto Deactivate within the Particle System, which was a good suggestion by someone else, but the particles remained frozen. So along with unchecking Auto Deactivate, I also found that in the Particle System settings, Seconds Before Inactive was set to 0. I changed this to an arbitrary number of 10, since my sequence was less than 10 seconds long, and this solved the problem. So changing the Seconds Before Inactive to a number greater than the number of seconds within your sequence may help.

Hi,
None of these fixes seems to work for me, has anyone found any other solutions?
Work for me.
Thx lot bro’
