vlado do we need a new naiad2vrscene?

Ideally not; the problem was in V-Ray...

finally after some time i manage to test almost everything and came up with interesting results,

the rendering (particle flick) probl is gone, but there is an another probl with rendering, here it goes:

here are the details on the probl

------------------------------------------------
Vray particle render count

133mil particles - uses 21gb ram - 4 vrscene

naiad pts cache01 - 10271703 particles
naiad pts cache02 - 41968383 particles
naiad pts cache03 - 46583411 particles
naiad pts cache04 - 34664219 particles

Render Script:

from vray.utils import *

for ii in range(1, 2):
frame1='pts_cache01.%04d.vrscene' % (ii)
frame1='e:/vrscene/'+frame1
print 'loading:', frame1
appendSceneContent(frame1)

particles=findByName('Pts01')
node=findByName('box01_ptsShape@node')

if len(node)>0 and len(particles)>0:
node[0].set('geometry', particles[0])

for ii in range(1, 2):
frame2='pts_cache02.%04d.vrscene' % (ii)
frame2='e:/vrscene/'+frame2
print 'loading:', frame2
appendSceneContent(frame2)

particles=findByName('Pts02')
node=findByName('box02_ptsShape@node')

if len(node)>0 and len(particles)>0:
node[0].set('geometry', particles[0])

for ii in range(1, 2):
frame3='pts_cache03.%04d.vrscene' % (ii)
frame3='e:/vrscene/'+frame3
print 'loading:', frame3
appendSceneContent(frame3)

particles=findByName('Pts03')
node=findByName('box03_ptsShape@node')

if len(node)>0 and len(particles)>0:
node[0].set('geometry', particles[0])

for ii in range(1, 2):
frame4='pts_cache04.%04d.vrscene' % (ii)
frame4='e:/vrscene/'+frame4
print 'loading:', frame4
appendSceneContent(frame4)

particles=findByName('Pts04')
node=findByName('box04_ptsShape@node')

if len(node)>0 and len(particles)>0:
node[0].set('geometry', particles[0])
--------------------------------------------

so is there a way to optimise this and render more particles?
also vray waits a lot before render even starts ~10min per frame?

cheers

Probably there are things that we can do, but I would need the scene to profile it and see where that time (and memory) is spent. I don't think we've ever tried rendering that many particles before... I'm actually surprised they render at all

In general though, for large amounts of particles I think we would need to expand the .vrmesh format so that they can be loaded on demand, rather than all at once...

wow that was quick

ill see what i could do about the files coz they are very very large ~25gb......

Hi vlado,

i manage to pack everything, u can download from here

http://www.sendspace.com/file/6swf2x

there is also convert.bat file to convert naiad emp to vrscene,

let me know if u need anything else for this probl

cheers & thx
