Problem - vrscene seq

[vlado]

can u just tell me is it possible to convert emp particles in something else then spheres, so user could define later in render what he would like to use?

You could make them points or streaks, if that works for you...

one more thing and wont bother u today any more

these points or streaks they r in naiad2vrscene?

is there a flag for this option?

coz if i got it right, when i convert naiad2vrscene i define radius for mesh spheres, right?

1.

from vray.utils import *

for ii in range(1, 10):
frame1='flood_FLUId_v002.%04d.vrscene' % (ii)
frame1='r:/jobs/naiad/vray/vrscene/fluid/'+frame1
print 'loading:', frame1
appendSceneContent(frame1)

particles=findByName('Particles')
node=findByName('pCubeShape1@node')

where i add render type in this code

2. any chance to write vrscene in binary for smaller file

T where can i find samples on thes py callback?

thx

1. add particles.set("render_type", 6) at the end
2. I don't think it is easy to do

T where can i find samples on thes py callback?

Here is the official documentation (including some examples): http://www.spot3d.com/vray/help/maya...ene_access.htm

Here you can find info about the plugin parameters: http://www.spot3d.com/vray/help/maya...cleSystem.html

Is it possible to share the maya scene, too?

Edit:
Can you please post the commands you use to convert the emp to vrscene files?

Also, if possible can you share the water layer, the foam layer is too transparent and I'm not sure if I can see where is the problem?

hi T, sorry for delay, i was busy...

its a bit large ~800mb and maya scene

hi vlado & T,

did u maybe download these emp's, or are there any progress for this probl?

cheers

[vlado]

Yes, I got the files; looking into it now.

Best regards,
Vlado

great thx for ur time......

[vlado]

This is fixed in the today's builds, sorry for the delay. It happened only for static particles without motion blur. Btw, if you do need the motion blur, in addition to turning it on you need to set the "nsamples" parameter for the particle node to 0 in the vrscene so that the result looks like this:

Node pCubeShape1@node {
  transform=...;
  geometry=Particles;
  material=VRayMtl1@material;
  nsamples=0;
  visible=1;
  user_attributes="";
}

Or else you can simply animate the original cube.

Best regards,
Vlado

great vlado thx, ill try let u know how everything went

cheers

Hi,

I've been following this thead closely and been trying to render naiad particles myself. I'm having trouble getting motionblur to work. I've added the nsamples=0 in my post script, but whenever I turn on motionblur my particles explode.

My mb settings is:
duration .5
interval center 0.0

[vlado]

It looks like the velocity is with wrong scale (or just plainly wrong). Can you get me a small sample of the .emp file?

Best regards,
Vlado

I send you a file.
