I’ve been searching around for an answer to this, but to no avail, so I figured I’d ask here and see if anyone has any insights.
I’ve been using 2.8 and Eevee a ton lately, just to sort of explore and play around – I’m well aware that it isn’t yet fully feature complete and all. The one limitation I seem to have run into is hair.
I can get it to look decent enough in Eevee, but there seems to be a limit on the number of hairs, based on complexity. So just the simple, default hair lets you do around 16k total, but if you add extra steps and other intricacies, that number drops.
Once you cross that magic number, the entire hair system simply vanishes. I’ve attached a simple demo video to show what I mean.
As far as I can tell, this has never been an issue in 2.79. It would get REALLY laggy, if there was too much hair on-screen, but it would at least still render.
Does anyone know if this is some new 2.8 safeguard to keep the viewport fast? If so, can it be disabled? A bug? I haven’t seen anyone talk about this (although it’s entirely possible I just suck at searching), and it seems like something a lot of people would be affected by.
I use hair a lot in my work, whether for its intended purpose or for procedural stuff like trees and grass, so having to work around some uncrossable limit would be a bummer.
