how to render multiple frame?

[doridarien]

hi guys

I'm using luxmaya,

and I'm just wondering is it possible to render animated scene with luxrender?
not single frame, multiple frame like 100 frames at least.

if is it could anyone advide me how to do it?

Thanks.

Yes you can do this with LuxMaya. You need to enable the 'Render animation' (on the Scene tab) option and choose 'luxconsole' as the renderer type (on the 2nd tab, I forget what I called it) on the Exporter GUI.

You also need to set the render frame range, I think this is done with the controls near the bottom of the screen - i.e. the frame preview range. If that's not it then it's set in Maya's rendering options as per normal.

BTW, moved thread to the Maya forum.

Hi

I'm Trying to render animations and i have no problem export the scene to frame sequence.

but in luxrender it renders first scene and never stop rendering.how do i move on the the next frame?

You need to set the haltspp parameter in the Film settings, and use the Console renderer, not the GUI.

Thanks!
I finally got it working.
but the image is very noise, low quality.

I'm using Halt spp -1
with low discrepancy -16 pixelsample with "tile" sampler.

should i increate number of pixelsample of 16 to higher to get better quality? or increate the Halt spp?

Thanks.

To be honest, I'm not sure how these parameters work together. I hope someone else can explain.

Hi,

The number of samples for lowdiscrepancy indicates how many samples the sampler will compute at once for a given pixel. So the higher the value, the better the stratification and the quality, but it'll take more time. Those values can only be powers of 2 (they will be rounded to the nearest higher power of 2 if you specify a non power of 2 value).
The haltspp parameter tells lux to stop after at least that many number of samples per pixels and after a full rendering pass, ie if you told the lowdiscrepancy sampler to compute 16 samples, it will stop at a multiple of 16 samples per pixel (all values of haltspp between 1 and 16 will stop at 16, all values between 17 and 32 will stop at 32, ...).

The best result will be achieved be setting the number of samples of the lowdiscrepancy sampler to the estimated value to have a clean result and setting haltspp to 1. However due to the power of 2 rule, you might find that it's not fine grained enough, in which case you can select a lower value for the sampler and set haltspp to your target, the stratification of samples won't be as good though than with the first method.
