GI/Net Render
Trying to wrap my head around this…I’m trying to use Net Render with a scene that has GI. Net Render crashes the majority of the time when going from loading the GI pass to the actual render.
Since the GI is not distributed, can I render a GI pass on my local machine and then drop that .gi file into my Net Render folder, and render from that point?

What GI settings are you using?

IR + QMC Net Render
Diffuse Depth 1I set the irradiance cache levels to medium, or even low when I can get away with it.
I like Net Render, I like the results I’m getting it’s just that it’ll hang up at night, in my office, when I’m not around and I come in the next morning and nothing’s been rendered.
Is Net Render known to be buggy? I thought Lightwave’s net render was bad but this is almost as bad.

Hmm, I haven’t heard of this problem before.

I did a test last night. I sent one copy of the scene to Net Render (with 15 clients) and rendered another copy of the scene locally. I went in and checked it this afternoon; the net render scene was hung up, the scene I rendered locally had already rendered 30 frames (of 140) and had obviously completed the GI pass.
So back to my original question 🙂 Do you know if I can I take the .gi file that I rendered locally and use that in my Net Render so that it will render faster via net render but not crash, assuming it’s the gi pass that’s causing my system to hang up?
And if so, where does that .gi file go? Do I load into the GI panel and/or copy it into the folder for Net Render to see it, along with the scene files/tex files? thanks.

I’m not sure if you can upload a GI pass to be honest with you. My understanding is that when you render a GI scene on NET every client calculates the prepass and NET uses whichever one finishes first.

I wonder where NET render saves the GI pass then? I don’t have the files in front of me so I can’t look. If it saves a physical .gi file, I would assume you could load your own?
Oh well, thank you for trying to help me. I’m sort of wondering if it has something to do with the scene file size as well. I’ve used NET render for 3 scenes; 1) Just a test scene with a cube, that worked fine 2) A scene file that was about 15 mb, this worked fine at first but has seemed to get progressively unreliable 3) A scene file that is over a gig, which I’ve never gotten to work on NET render.
That file is actually over 2 gigs (don’t ask) and when trying to load that, I would get an error message. As soon as I can get the file under 2 gigs, I don’t get the error messages but it gets hung up. I’m assuming 99% of the people here aren’t working with 2 gig C4D files!

Yikes. How much RAM do you have in your machines, and what OS?

Yeah…the scene file is of a highly detailed sports stadium. I’ve run into other problems because of the file size but have found workarounds to those. The actual scene file is 3.5 gigs with everything but I have yet to use that scene file in production. It’s mainly from all of the seating which is modeled pretty accurately; the render instances boost the file size a lot.
I’m using a compositing tag, turning off the GI for the seating and I thought that would take a load off of the GI pass, and it does but I guess not enough.
Anyway, I’ve got 12 gigs of ram and I believe I’m on Mac 10.5.8.
