When I render my scene the particle system often gets screwed up, such as in this video.
What doesn’t really make sense, is that if I play the animation in the viewport, it can run it at a constant 60fps without a broken particle system. Note: I’m using OpenGL render active viewport.
I know that caching/baking the particle system would solve these issues, but if I bake to RAM, Blender just CTD after ~100 frames. If I cache to disk, it takes forever, getting exponentially slower. It can’t be the speed of my HDD, since I’ve tried using a RAM disk, and it was just as slow.
