Description
Well, this is my latest render.... And there's something very wrong here. This took 82 hrs using MLT at 146 passes.I guess I have one big question how do I redner a big, complex model( 1mill polys) with several emitter light sources and kerky materials in under 10 hrs?
my computer is a dual core 2,41 Ghz 4600+
2,87 GB ram

one way around the speed problem might be to see if you can upgrade your video. i mean, if you are using a built in video, that's gonna run everything through the main chip, KILLING renders before they even get far. however, a speedy video gaming card, just might give you the edge. it would be worth the cost if it made the process quicker for you, no matter the size of the page or swap detail. btw, love the ideas here. keep it up...

Hi mate, sorry for the late reply, It's been summer and I have been away from the net. Thank you for the tips! I may just have to look into that. Mind you my comy is 8yrs old so I'm not entirey sure it's going to be worth it. Hopefully I'll be getting an we one soon. Also thank you for liking my stuff!

Kerky handles polys pretty well but as soon as you start adding light sources the complexity and render time goes up by orders of magnitude. There's not much getting around that short of new hardware :-/. Is there any way you can cut lights out of the model and do the effects in photoshop afterwards? For example, if you're rendering those holographic displays as actual luminous material, you could eliminate that from the render and superimpose a "greenscreen" image of the display graphics over the kerky render, and it would look roughly the same.

Thank you for the tip, though PS is out of reach for the time being, so I have to do it the hard way for now. At least it makes me have to explore Kerky to the point that I can make some pretty decent shots in the future.

Thats superb, what photo filter process are you using to get all that shadow grain?

Thank you! Err.. Photo filter process..? I'm using Metropolis light transport if that's any help.

Oh and in answer to your question - don't use kerky for your renderer, there are much faster free and trial photorealism renderers than kerkythea.

Okay thanks, this sounds interesting, especially the freeware which one are you thinking of?

another idea would be setting up a render farm with the network render option. only really effective if you have a computer of a similar level though.
I think ~ACXtreme might have the measure of it

Render farm? You've lost me mate.. besides I only have this one and a couple of ridiculosly old laptops, he hehe..

kerky has a very neat network render option, it takes a bit of setting up but it does work quite well sharing the render load across as many computers as you'd like to add... speeding things up. however adding some ridiculously old laptops aren't going to improve things much... believe me I know. my pc is a slightly lower spec than yours and i tried a network farm with a single core pc and an old laptop... it was about as useful as a chocolate teaspoon

He he he, chocolate teaspoon, that was a good one, he he.

If you have more than one computer you can split up the rendering job amongst them. It's called a network render. Lightwave supports it with ScreamerNet, I believe. Not sure about other packages.
Basically it divides the render time by the number of nodes in the network, since you can render N frames at a time instead of 1.

Aha.. I only have one though.. Thanks anyway!

my computer is a dual core 2,41 Ghz 4600+
2,87 GB ram
One does not render big scenes with dual core computers
...I mean I have 8gb ram and 6 core AMD 1090T @ 4ghz and scenes still render for 20+ hours that have around same amount of polys.
You must get more RAM for starters, at the moment I think the system is swaping render info between RAM and pagefile on your HDD and that HURTS render times for starters
then comes your old CPU... I mean you are using GI etc... there's shitloads of calculating to do... 2x 2,41 is just too slow.. + It seems like it's a old AMD cpu with little L2 cache etc...
soz mate but there's no easy way out.

I know f...all about computer internals, but you're probaly right. The pc is getting on 7yrs now so..
Well, I have one more option, and that is to cut the model up into small sections and render one part at a time, then deleting everything that is not in the image. I'll try that before I put my car out on ebay, he hehe...

yarrr... car vs rendering pc...
