HELP on render times

Post by larry_g1s »

Hey everyone. I could really use some help. I've got an animation that is kicking my butt on render times. It's about a 500 frame clip, at 720x350 resolution, that is rendering out at 30 minutes a frame on an Intel Quad-Core processor with already cached GI. :shock:

I've attached a render with my settings, and a screen shot of my basic set up. If anyone can help me with some decent settings for an animation I'd greatly appreciate it. You can see that this is not getting a whole lot of natural lighting from the outside.

Instead of "million" area lights use only a few long ones. This will certainly reduce render time.

Also your photon power on the Photon tab is realy low (0.04). I don't think this is good. Use 0.3-0.5 instead. Then you will also be able to lower the area lights multiplier...

Also try switching mode for your thousand arealights.

Okay, I tweaked some settings per the comments and fortunately I believe it dropped in render time, but still at 17 min with zero AA. The illumination also looks a bit more natural looking too, which I like. SO thanks again there. I've obviously got some more tweaking to do but thinks for the heads up on some of these.

Man...still getting 30min render times per frame on a 720x350 resolution. What's strange is that it doesn't change much on the render time caching the GI. It goes from 29/30minutes to 25 minutes. I mean 5 minutes less per frame is 5 minutes less per frame, but come on...this is Kray! with a quad-core processor and on a 720x350 resolution.

Did you reduce the number of lights? Did you perhaps try without area lights and just use lumi polys instead?

Do you perhaps have huge plane outside? If you have huge model or even just some points far away in space it can slow it down a lot because calculation must be done with much bigger numbers....
I suggest you try removing objects and see what is causing the slowdown...

I think there's too many area lights. kray slows down a lot after using more than 5 area lights. I dont know why. I tried to render an airplane interior with many light fixtures(15) and it rendered as long as lw but AA much better in kray of course. What I hope to see kray do are interior renders lit by artificial lighting. I haven't seen commercial and restuarant spaces in kray yet with more dynamic lighting. Its mostly dayllighting I see.

In Quality tab try to change Recurse Min/Max to 1/4, 1/3 or maybe even to 1/2 and see what will happen, as well you might try lower Area light threshold treshold

Have you tried exchanging all your arealights to luminous surfaces? If you do you will have control per surface if you want. I suspect that will be much faster than using Arealights.

Heres a simple test setup that rendered in 2.5 minute on my quadcore.
