Cinema 4D & VrayforC4D

Deadline
1

Hello,
I have recieved a trial for deadline 5 for 4 slaves. The setup of the render management system went well, and I use the supplied “submit to deadline” python script to start rendering across the network.

The four slaves render as normal, but my problem is the images produced by network rendering are slightly darker than the images produced localy. I have been in contact with the creator of vrayforc4d, but we have not figured out what causes this difference in the rendered images.

Have tried different approaches to solve this problem without luck:

  • render out 32bit 16bit 8bit
  • Linear Workflow both on and off
  • with and without color management in C4D
  • tried different scene units (cm and m)
  • output to exr, tiff, png

My test scene in Cinema 4D is just based on shaders with colors and normal arealights. So missing textures is not a problem.

Has anybody else had similar experience?

Best regards,
Kevron

Hi Kevron,

We haven’t heard of this problem before. I guess the first thing we could do is determine if the problem is related to Deadline or not. If you check the render logs for the job (right-click on the job in the Monitor and select Job Reports -> View Log Reports), you see that it contains the executable and command line arguments used to render the C4D job. You can try running those exact same arguments from a command prompt on one of your render nodes to see if the same problem occurs. If it does, then at least we know that Deadline isn’t the cause of the problem. :slight_smile:

Thanks for your reply rrussel, I’ll test it out and see what happens.

Hi Ryan,
Deadline 5.0 is ruled out of the problem. Doing a command line render with C4D gives me the same difference in the rendered image. So there is something fishy with nogui render and VrayForC4D.
I´ll investigate further :slight_smile:

I think I solved it. Having DeGamma installed in the pluginfolder, created some sort of a conflict when commandline rendering with vrayforc4d.
After removing Degamma, the renders are identical.

Hi Kevron,

That’s great! Glad to hear you were able to figure out the problem.
