ı am really amaze with exterior lighting in maya because of taking not desired result ... i search lots of doc. on net but i didnt find a good source of exterior rendering. i am realy curious about which settings you use when u rendering...

i use this setting but not taking good results

1.disabling default light, making sphere with white surface shader
2.final gather
3.spot light with reytrace shadow and linking with mib_cie_d

am i change to max ?
or u know any good tutorial when i watch it not making is impossible..

thanks

these are three best techniques

1) mental ray's Sun + Sky - most realistic, but difficult to first understand what's going on "under the hood"....gamma correction, lens shaders, physical mateirial properties. create this under render settings window.

2) image based lighting - with a direct light this is the easiest setup. found under render settings window

3) dome lighting - fastest method but it dont have nice "light bounce", but this can be faked.

use scripts like this for the third method, very fast setup

none of this will get perfect renders straight off. it takes a long time and lots of patience.

use physical sun and sky along with final gather for something like that

play with the red/blue balance and saturation to get those nice warm sunset tones

Ah that's the effect you want.

I think second image was created using IBL, I don't think any sun + sky was around in 2004. Not sure about first image, possibly IBL lighting as well, but it's harder to tell.

In any way, all you really need to do is have a really blue sky and a complementary sun colour that's why those images look so nice. It's not a physiacally accurete render so I think IBL would be the best approach as you have more control over the colours and saturation of these colours.
