Hair particles causing cycles render to hang on 2.9 I don't know if anyone else is having this issue but for some reason a hair particle system is causing cycles renderer to hang at the initializing stage and I have to force quit blender.
If I turn off the particle system the scene renders fine.
I've narrowed it down to the children section, I have it set simple which is the best look for the hair I'm rendering however if I set it to interpolated the scene renders fine but the look isn't what I want.
Can anyone help?
I'm using a Macbook pro 2018. OS Catalina 10.15.7
Blender version 2.91
After some experimenting it seems I was wrong about the memory. I've learned that having too many particles definitely affects memory and render times.
To combat this I reduced the number of children by half which made a huge difference but then the hair looked too thin, so to compensate I thickened up the roots.
It seems that my system will alert me if blender is out of memory when using too complex meshes but not with hair particles. Also my render times have decreased significantly.
