Different renders when using Net Render vs Local
on Jan 19, 2015 at 3:49:29 pm

Hi All,
I came across a strange thing on my current project. I've been using Net Render over Team Render (had a lot to do with me not being local). I've rendered a bunch of scenes and occasionally rendered them locally due to availability of our render servers. I've noticed a substantial difference in the final render when rendered locally. I was wondering if anyone has seen this, and can give me an idea of - a)what's causing it, and b) How do work around it?
C4D Studio V15, Net Render V13 (I've been using Net 13 for about a year since updating to V15, and never ran into any problems)

LOCAL



NET RENDER

It's generally a bad idea to use difference C4D/NET versions -- especially if your NETR is older than the C4D version you used to create the scene. Some things aren't backward compatible.

Hi,
Yeah, I hear you. I've been using this method for about a year since we started using V15. I had some issues with VPN and Team Render. I did some tests yesterday, and I'm trying to eliminate other factors. For example. I was rendering to H264, and when I rendered to Animation compressor, there was a definite difference (or should I say the difference between that render and the local render was less). I'll do some more tests, and see if I can't find anything else out.

Hi,
For anyone interested, I thought I'd follow up on this topic.
We can't use Team Render right now because it doesn't work with stereoscopic cameras. So I was back to figuring out the color shift between V13 Net renders of V15 files.
It's actually pretty simple -
In V15, Specular and Specular Color were combined into 1 channel.
When I opened the V15 file in V13, I saw that the Noise shader that was limiting the specular in V15 was loaded into the specular color in V13. This channel was turned off. So, when I turned that on in V13, the renders looked identical. I guess I've got a workaround.
