Particle flow - building static raycaster accelerator taking forever

[stevesideas]

Im animating some particles being thrown so the particles start from a small bundle and spread out over time. When rendering, the memory usage goes up and up till the system is using 22gb out of 24gb and the "building static raycaster accelerator" takes forever.

If I use scanline it renders fine (but not with the quality I require). Really need some kind of solution to this as the project needs to be delivered this afternoon...

Im assuming this problem is occurring because of the particles overlapping at the beginning. I decided to use 2d circles as the shape instance and this seems to have resolved the issue...luckily the quality isn't affected by much.

You could also try setting the min. leaf size parameter for the raycaster to something larger than 0.0 (f.e. 0.001 or something like that).
