If you look closer at the reported stats you will see that there are just
over 6000 objects in the scene. That is a walk in the park to parse. It is
when you have 50k or more objects that the memory and parsing overhead
become really noticable. What surprises me the most is the scale of the
object vs. the number of hairs it took to get full coverage. The camera
is a couple hundred units away from the object which implies to me
that it must be near a hundred pov units in size to fill the image the
way it does. I can't imagine how the object count is so low and the
coverage is so good. It may be a trick of the mesh compression utility
that Warp is running it through.
