Final render more than 12hours, please help :(

[leuska123]

Hello. I need help with render options. I am using a lot of glossy and transparent materials. I would like to have really highquality render, but it takes a really looooooong time...more than 12hours. I have on my scene transparent textures, glass, a lot of omni light over the barcounter (over absolut bottles) and in other scene i am using a ice material. It is a really huge project, but I need to decrease render time on half. I dont know where is the problem, but I have speed computer and need high quality picture like I post you.
On the picture is not final project, because I correct a lot of thing, but I need help with improving my render options.

These are my scenes

Use IM + Light Cache instead of DMC.

OK, thank you. I will try it, but do you think, that only this setting will hellp me to get good result and almost half time of rendering process?

Can you help me, where i could find some tutorial about render options, where will be explanation of every setting which i could change? I dont know if you understand me, because my english is poor, but I mean detailed explanation about render options

Yes, that why I wrote it.

You have to realise though that interior scenes with large areas of high-subdiv glossy materials will always be very slow to render, it's just a consequence of the extremely complex calculations having to be carried out to trace the light as it is bounced around the scene multiple times. If you think 12 hours is bad, V-Ray is at least ten times faster than any other render engine I've used. Maxwell would take more than 12 days to render your scene.

If you have more then one computer sitting around (even older ones help a little) you could take advantage of distributed rendering. In ideal conditions that makes an obscene amount of difference in your render times.

yea - at my office I've made sure to grab all old computers as they upgrade to newer. I now have 6 old P4 comps ~2.6-3.4Ghz to assist me. Even as crappy as they are - they help loads.

Been doing some calculations - getting some cheap all-in-one motherboards with mid-end quad-core processors isn't that expensive. For the same price of a high-ish-end desktop computer you can build a nice little render cluster with lots of CPU cores. And you don't even need Windows license for them. Just install Linux with Wine.
