Problem - vrscene seq

[bazuka]

im not sure how can vray know when to load vrscene file and in what moment?

ill try tomorrow and will see, but i dont think this will work..

[t.petrov]

It won't work.
Can you send us a naiad files we ca use to do some testing?

[bazuka]

yes sure, let me upload them

thx for your time

here you go

Thank you.

Here is the new version of the tool: https://ftp.chaosgroup.com/vlado/vra...ne20130418.zip
I've added another parameter at the end which controls the target frame.

You have to convert the frames with commands like this:

naiad2vrscene input_file001.emp frame001.vrscene Particles 0.1 24 1
naiad2vrscene input_file002.emp frame002.vrscene Particles 0.1 24 2
naiad2vrscene input_file003.emp frame003.vrscene Particles 0.1 24 3
naiad2vrscene input_file004.emp frame004.vrscene Particles 0.1 24 4
...

Then in maya you have to use python code like this:

from vray.utils import *

for ii in range(1, 10):
	frame='frame%03d.vrscene' % (ii)
	frame='path to the output files'+frame
	print 'loading:', frame
	appendSceneContent(frame)

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

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

Using this workflow I was able to render animated sequence with Maya.

thx T, you are the man

cheers

[bazuka]

T,

i have a question, is it possible to render these particles as points not as spheres?

thx

[bazuka]

there are some probl in converting process

i could upload them all and when u have time to take a look at them?

Yes,
You can set the renderType of the GeomParticleSystem plugin to 6 using the python callback. See here:

render_type: integer = 7, 3 - multipoints; 4 - multistreak; 6 - points; 7 - Spheres; 8 - Sprites; 9 - Streak.Everything else gives a warning and renders as spheres.

What problems, I'm not good at guessing?

[vlado]

We could extend the appendSceneContent() call to work with wildcards, if you think it will help... so you could write appendSceneContent('my.*.vrscene') and it would load all matching files...

i will upload some screens and ull see

T, i dont understand this 1st part about render type? why do i define radius when i convert emp2vrscene?

here is a mov, watch it frame by frame and ull see what i was talking about

This might be a V-Ray issue, but we will need some way to reproduce it here.

[bazuka]

that was quick vlado,

im uploading emp files so u can try convert them and see if u can reproduce bug there, should be UP in a few min

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?
