In the end, I need to render a scene at 8000x4000. Currently I am able to render the scene at 1600x800, but at 2000x1000px the computer hangs on the first pass of the irradiance map. After the whole night, it is still on zero percent. If I drop the resolution slightly to 1000x500, it is able to render the scene in an hour or two.
More information:
Using vray for rhino 2: Computer has 28gb ram, i7 4770k processor.
It looks like the computer wants to use as much RAM as is available. At the 1600x800 scene it uses the whole 28gb of ram.
Questions:
Is there anything I can change to be able to render the scene in the irradiance map settings? Is there a way to trade RAM for speed, so that the render takes longer, uses less memory, but is completed in the end?
I have 3 rectangular lights, 8 spot lights, no sun, using GI hdr map to light the model through the environment settings. Is this a complex scene? If so, what are the best settings to use to aid processing of the scene?
