I’m working on a scene that shows a horse in a pasture. I’m using hair particles for both the horse’s hair and the grass. This seems to require a very large number of particles in order to get a satisfactory result, and it’s using a very large amount of memory. To render the horse alone (without the grass) requires the whole 8 GB of RAM I have available.
Obviously I could render the horse and pasture in two passes and composite them together afterward…but even horse or grass alone pushes the limits of my computer. Are there other ways to reduce memory consumption with large numbers of hair particles?
