Quite a lot of energy, if you compare it with bulbs efficacy:

Sun spectral radiance at 500nm: 2073593016418.64060 Wsr^-1m^-3

start reading the posts at the bottom of this page and the next, will help you setup Blender to allow proper camera positioning - I had problems before as well

and download these video tutorials - the first one especially, is very helpful for setting up the preferences and camera to work better

Especially in interior scenes, that might be the case...

I *think* I've got a fix for that - seedvalues are given randomly, before each render in indigo... seeds have sort of a special shape - each seed value has slightly different patterns....

so, after some times, these patterns might start to repeat, slowing down the process....

my guess is, that after it *seems* to not change, anymore (it still does, but slower and slower), is, that you need to resume the render

I wonder, if it was possible, to add a "random seed refresh" setting, that refreshes the threads seed values, after a given time (if you render a preview, you'd set that pretty high, but in longer "final" renders, you set it to very low ) - Ono, what do you think about that?

that's where having a quad core comes in handy with 4 different renders going and 4 different seeds

Cinema4D, but I also use the free version of Google Sketchup for the very easy modelling and nice exporter for Indigo called SKindigo for quick setup and render. Sketchup is faster and easier to use than all other programs and exporters - You can draw a room and add windows, plus Exit Portals really quickly. Not so good for complex modelling though and a bit slow with high poly counts, but you can import 3DS files and use Proxy models and instancing to get around that. I recommend it to anyone who wants to get into Indigo quickly., and there are Tutorials in the tutorial section of this forum.

I Also use Blender and Blendigo because it's free

But it probbaly has the most complete exporter, but I'm not that comfortable in Blender yet.

I'm a man

OK Thanks - I want to try free version of Sketchup - just for interest

Hey CoolColJ, I thank you twice ! First because I missed vux answer (sorry mate), then because I have the same sensation he has with blender's camera. But as far as I'm concerned that totally prevented me to use Blender.

Even TopMod is using Maya's camera navigation system

I agree

Ono is there a chance to set seed???

May I set different seeds for two identical images and compose them in Photoshop, and experiment with blending mode???

If you start more than one thread, the pic uses more than one RNG Seed value

(In theory, there could be 1000000 threads from indigo: from Seed 000000 to Seed 999999 - at least that's what the range would allow

[I never saw a value, that doesn't use all the positions, though])

vux · Post by **vux** » Thu Sep 06, 2007 4:35 am

i dont understand how to control seed - I have 2xXeon and i set 2 threads - but how this interact with seed?

Kram1032 · Post by **Kram1032** » Thu Sep 06, 2007 4:48 am

seed is chosen randomly...

every single thread starts with a random RNG seed value

- no control at all...
