Give at look at this heavy one!

Hi everybody! Recently I did this render (godzilla not included =D )
I actually don't like their project so much, but they like it and this is what they want.. and they lead.. so..
Anyway I'm not posting it in relation to the fact of it being beautiful wich is absolutely not (IMHO) but I'm considering the heavyness of the render itself..
I'm not sure this can be considered an heavy sketchup+vray render, but I can ensure this is pretty heavy for me.
I mean, till a short ago, I was not able to complete such heavy renders, due to the fact the render often crashed cause the 32 bit lack of ram issue..

Actually here you have a lot of high poly geometry, 737 components repeated in 10700 instances or so + about 900 groups, tons of lights + invisible lights,
about 140 materials with many bumps, transparency, displacements, blurry reflections, quite high render engine parameters, lens distorion, hi-res etc..etc..

It took me here on sketchucation reading interesting discussions about handling those lack of memory issues whith some tricks and workaround I didn't know and most of them worked really nice,
for example the fact that you should subdivide a mesh for better displacement performance, or that component modeling is the key,
or that you can smartly place png elements for vegetation and characters instead of modeled ones etc..
anyway I think it could be also better generally optimized with other triks I don't understand well like the whole saving exr, saving maps and channels stuff..
or maybe using ies lights (I'm not able) could save some memory instead of using tons of hidden spot/rectangle lights to produce the light effects they wanted on walls..

I think if would be useful if we post our most heavy works to discuss the proper general workarounds to fight agains the big bad memory limit issue..
