vraylightselect and max batch render

[fraggle]

Hello,
I can't get the vraylightselect to work with the max batch render. Other vrayrender elements render fine but the vraylightselect pass are black.
Without the batch, it render fine!

Any idea?

Thanks

Can you be more specific and describe your workflow, because everything reneders fine in my tests. What is your export file type ?

[fraggle]

Thanks,
I'd tried exr and tga in the batch render.
Batch render can't use the vray frame buffer, render is done within the max frame buffer.
All pass are saved but return black for lightselect while other pass like renderId render fine.

Hmm exr, tga, pngs - it's all OK.

Max and Vray versions ? Can you upload a simple scene here ?

[fraggle]

Sure but As our deadline is so tight, we wonder if there is a way to submit the job to Distributed rendering to the same workstation? Can we submit the job to DR, so another instance of max will start to render the job in the background while still working on the scene? Like In BB?

We usually use BB to submit different camera view but under max 2013, the BB return an error message and we can't get rid of it for now. We are waiting for Autodesk support at the moment, but any faster solution ios welcome.

You can use the 3dsmaxcmd.exe command to render scenes from the command line; you can also run the backburner server on your workstation, but as you said that this doesn't work, it's probably not much of a help.

Why you need sending the job to DR , when you can start two Max's , one for rendering , and a second one for working on the scene ?

[fraggle]

Sorry, It was not clear.
We would like to queue several render to the main workstation. As BB is faulty at the moment, we are looking for another solution and are wondering if Vray as this option integrated somehow.
The batch render may have solve our problem but we face vraylightselect black render while using the batchrender.

[vlado]

You can write a simple .bat file that calls 3dsmaxcmd.exe for the scenes that you want to render.

Best regards,

Maybe try deadline? It's free for up to 2 render nodes.

[fraggle]

Thanks,
We tried, but so far no result. Got an error code while rendering.

[vlado]

You can maybe try to render to a multichannel OpenEXR file and then extract the elements, if the problem is somehow with the image saving, and not something else.

Best regards,
Vlado

We find out that doing again the vrayselect process finally works, but after some test, switching to batch or max frame buffer or whatever (can't find exactly what create the problem), the vrayselect render black again.
To make it works we have to make the final render right after the vrayselectlight is done otherwhise it render black (either save file or the buffer).

Does the issue persist only with one particular scene? Can you attach an example scene with that problem?

[fraggle]

will try to recreate the issues and send you the file.
Thanks
