Prepass rendering with backburner problem.

[STUDIOS_GARNIER]

Hi all v-ray user.

I’m encounter a problem with mi GI Prepass rendering.
Symptoms:
When the prepass is calculated on single computer with 5 RN, some frame crash. 3DSMAX shutdown and restart the same frame.

The part of server log is (sorry for French part, I’m working with Win7 FR !):

The final images is looking good, no problem with GI !
If I re-render the same project, the problem appears at a different frame!

Working context:
Network configuration:
-1 computeur for rendering (Win7 x64 – max 2016 up to date, V-ray 3.30.03 up to date)
-5 Render node (Win7 x64 – max 2016 up to date, V-ray 3.30.03 up to date)
-data stocked on Virtualized Win serv 2012 R2 (+ Exterme-Z IP for our Mac network)
-Network speed 1Gb

V-Ray GI configuration:


The scène particularity:
- 1 Container as open mod to edit in place.
- 1 Container as closed mod (sources path is resolved)
- Somme textures, light, camera, animated objects.
- Somme Visibility track of object it animated (1 to 0 as stepped interpolation)


I'm not sure but,
I suppose a file writing problem or networks resources access.

An body know the problem ? ?

The error that you get unexpected code -2 might be due to the BB server started as a service. Therefore could you please stop the service and start the BB server manually.
Also do you get the issue with a specific render nodes or it happens randomly? Moreover do you have ipv6 enabled on those machines?

Hi Zbravko,

Thank for your reply.

My BB it running as normal mode, i start it manually went I'm login on the PC.
It is not always the same RN.
It not a IPV6 network context.

For information, I just solved my problem!
Now i calculate mi animation directly in each RN, BB distribute the frame calculation on my render slave PC. (No V-ray Bucket distributed rendering)
It working good, and the Prépass issue (like dead buket !) it solved.
And the rendering time it reduced.

thanks'
