Hi, I have an issue with Still Renders. In this example I have a Cascade firefly emitter. In the viewport everything works fine. However, single image renders only render one firefly. I have already set the Engine Warmup Count quite high (have tried from 100 - 5000), but it dosen’t solve the issue. I have a similar issue with all emitters, such as leaves. They either do not render or render only a few. Niagra effects such as dust (seen in the image below) work fine and render correctly.
After testing by rendering a video, I found that no matter what the Engine Warmup is set to, the Cascade particles ONLY start spawning once the render actually begins. So the video started with one firefly and they spawned in one by one as the video progressed.
