Blender particles, export to Povray. Takes longer to render than I expected.

505000 hairs. They're exported as sphere_sweeps.

Unfortunately, has no faster way of display of curved hair of Povray

Looks cool.
As for render performance, I wonder if this not the kind of scene which
would benefit from Pov-Ray 3.7's relatively new "BSP (Binary Space
Partitioning) tree bounding" ?
I played with the option 3-4yrs back. For me it sometimes helped, but
more often not. I though, tend to do a lot of scenes with just a few
shapes. With 500K objects front to back maybe +BM2 would really help?

+BM2 was set. It took 12 hours to render (vs. 10s in Blender), although 500k
hairs is also a little overkill for something this small.

In my version of the exporter if hair aren't bent, it is possible to use
alternative of sphere_sweep - cone
On a screenshot time of a render of a ball is well visible: 4 minutes at the
same 500000 particles (processor - i3)
You can address to the developer of the official exporter (Mr) that he added the
same opportunity

I see. Unfortunately, I combed the hairs. So they're not straight anymore. Well,
it's just a test render. I'll hopefully have more interesting stuff to show
later.
