[Carrara]Carrara network rendering and MacIntel - Polyloop

gezer · 27th March 2007, 10:22

Hello all,
I've 4 Macs running OS X, networked, 3 of them as rendering nodes.
Network rendering works great.
I intend to buy an Intel Mac in the near future.
My question is, can it be combined with the rest of my Mac as a rendering host?
Has anyone had any experience in combining Intel and G4/G5 Macs, running OS X for network rendering?

It can but there currently some issues with GI. I'm sure it's being worked on but Intel and PowerPC calculate it a little differently and it shows in the final render with a slight tiling in the shadow areas.

So, the options are to fake GI (which is done a lot in the pro world simply because it renders faster anyhow) or turn off the Intel node while rendering.

Thank you for the answer Mark.
By faking GI, do you mean "Ambient Occlusion"?

No. The symptoms show up with AO also. Faking GI involves creating groups of lights to mimic the bounced light. Distance, fall-off and color need to have attention paid to them but it actually goes pretty quickly.

Even on my farm here, for longer animation segments, it actually saves time spending a couple of hours creating lighting rigs v.s. having a render go on for 18+ hours.

I wish an enterprising busines would do for Carrara what it did for Vue6 Infinite. That is, to create a for-hire render farm where you can send your work to be rendered. That's a life saver on tight deadlines. Maybe as Carrara keeps creeping into production environments and gets more widely adopted, it might happen...

That is an excellent idea Mark
