thx guys
just wish i didn't have to stream them, iv' only managed to view the first two of the bridge tutorial, and it took a few attempts to get to see them.
streaming media is always a problem for us here, we actually had to get a special d'load for some of the CmiVFX dvd's we bought

hey, sorry for the late reply!
here is some updated tests, i'm still getting slowdowns with different bucket sizes. I've used a much heavier geometry scene for my latest tests with some displacement and existing shadow maps.
here's the results:
bucket 16 raytrace
cores x2 4:25
cores x8 4:40
bucket 64 raytrace
cores x2 4:27
cores x8 4:16
bucket 16 micropolygon
cores x2 1:18
cores x8 3.58
bucket 64 micropolygon
cores x2 1:16
cores x8 4:17
avarage mantra memory use 1.9gig VM 1.89gig
rendering on:
dual Xeon quad core x5365 cpu @ 3.0GHz
XP 6bit

hey thx for the replies
Mark, i'm measuring wallclock time and rendering to mplay.
i'll try re-render the scene later today with a smaller bucket size(well thats if my 6k render for a print ad finishes today :roll: )
i'll keep u posted!

hey
i've also found mantra to be slow on simple scenes, but yeah it doesn't take much longer on a slightly heavier scene.
one of the big issues i'm having is multi threading. My new work machine is a dual quad core, now the tests iv'e done on simple and heavy scenes, mantra slows down to a crawl if i use more than three cores.
rather odd, check out the rendering times on a meduim size scene below:
all threads 00:02:38:shock:
one thread 00:01:04
two threads 00:00:42
three threads 00:00:37
four threads 00:00:48
this was with micropolygon, iv'e tried raytracing to0, it pretty much comes out with the same result
running h 9.0.762 on windows 64
i also tested it on 9.0.759

hiya's
i'm setting up some guide hairs on a imported obj sequence.
I'm coping a line to the imported obj's points, but because i need specific “styling” i want to Edit the copied lines “guides” after the Copy Sop.
How can i get the edited guides to maintain their shape? at the moment they stretch and rotate incorrectly when i hit play.
i know there is the re-orient attr. but i'm not sure how to implement it with a imported file seq. or is there another way?
anybody?
thx

hi
i was just doing some basic animation tests, when i ran into this little problem.
when i add a kink attr. to my fur the “kinked” fur's orientation get all buggerd up when my model rotates, does anyone know how to lock the orientation to the surface/skin?
check out this quicktime to see what i mean:
