keeps crashing

hairI have a scene with a head and some hair.

The hair is particles emitting from several objects. The head is geometry with three layer sss.

I can render the head alone or with some of the hair objects. The ones with less complicated particles, eye lashes and eeyebrows

I can render all of the hair alone, or with a simplified version of the hair.

But not both together! Anyone got any ideas?

Render them seperately and combine them in post?
I assume it’s failing because you don’t have enough ram. SSS and hair particles are pretty big tasks for the renderer.
