Hi all,

This topic was started on demand of Nuno Faria, who will explain his goal after this short introduction.

hi all,
i have been wondering..., and i thought maybe we (all) could do a simple test of light results comparison and share our technics how we did achiev the results.
what i mean is..., there is a model (simple one), and then...with any software we use, we could do a test of light distribution (radiosity | gi | fakeiosity).
so, the goal is....share as many tips and technics as we can in lighting distribution and see what is the software that do the more realistic lighting ( brasil | fr | vr | mr | max/viz rad | ls | or simply fakeiosity )

well...what do you all think about this?
here are the model files:
model.dwg
model.dxf

sun position: (rotation 346 degrees | elevation 23 degrees)
note:
1 - as a rad/gi artist, use just the sun and the sky as a light source
2 - as a fakeiosity artist use as many lights as you want
3 - use only a simple white material for the whole model
4 - do the best light distribution you can

best to all,
nuno

hi ppl ! oix nuno that´s a really nice idea!!!i think this is definitly a stage that all cg artist should think about..a lot of new thing´s are coming since gi and i´m really thinkin of "what next?". Lighscape has been definetly the best light distributor though with some strong handicaps (bumps, envoriment...).Well, some new things are out there (brazil,desktop radiance,...) that realy show some care and thoughts about arquitecture and envoriment.I´ve been trying brazil for two months now and lovin it for his speed and quality and specially his nowardays features (caustics, enhanced bump shadows,....).Well i´ll try to give this model a very nice light bath and post soon.
I believe this will be a fine topic

Hi Nuno,
First try with Inspirer
Processing 1 min.
Rendering: 15 sec

I think the model is in meters.. isn't it? it's important to know the scale units of the model.

can you put it a max file or 3ds... with the white material already applied and with the light of the sun ? it would be easier for everybody.

hi asim,
excellent start...i will post a test at the end of the day.
...tell us about your settings, like mesh refinement and other aspects that you may consider relevant.
thank you for the reply, i hope we could learn even more how to achiev the perfect light...

to Kib:
what makes you choose this or that software...???
i just want to know their capabilities, that´s all...
if anybody doesnt feel with the right knowledge in his own package to do this simple test, dont need to participate in this topic but must follow it.

best to all,
nuno

Ok here is the result I got with brazil (its a bit grainy but that can be sorted).
