Hair and FG, any point trying?

Seen quite a few people trying it, seen all of them failing.

Giving some thought at how FG works I can see why all hell breaks loose, not
to mention that MI_Hair primitives are not tubular geometry, so the way
landmark samples happen on them is radically different everytime the camera
moves, making caching (and consequent flickering reduction) absolutely
impossible.

Maybe somebody made it work in ways I dont know of, but as far Im
concerned its not something Im going to try anytime soon.

I got great results using 3 spotlights, with detailed shadow maps, and
rendering with rapid motion..

but I am checking the FG thing, as it gives even better results on one frame
basis, and renders faster with considerably

lower memory consumption..

just wanted to see if I am missing something regarding fur and FG...

Why not use a lightrig or something like that?

Hi,

I am trying to render alot of fur with FG (no shadow maps and Rapid motion,
just raytrace).

I am getting great results, on one frame basis.. but on animation, all
artifacts are set loose!

I've tried playing with all of the FG parameters... but it seems, like no
matter what I do,

I cant get the slightest improvment, artifacts wise..

any point keep on trying? any big trick, on how to do it?

cheers,

Oz.
