For daylight I used Standard Direct Light and Vraysky- I tweaked the sky to give me a deep blue colour. I have some bluish colour in white balance slot in Vray Physical Camera and I use Reinhard with 0,3 Burn Value too.
For dusk images I used a technique learned from the great Ronen :):
A lot of things really stick out with your renders but what really grabbed me is your lighting. I think it is among the best I've seen for arch viz, bright sunny day and hardly any contrast and your whites are white without being overblown.
May I ask if you used HDR or a sun + sky setup and what kind of tone-mapping process was involved (physical cam or just reinhard tonemapper). I find lighting the most difficult part of my job, beautiful work!
looks really great. I tried archicad to 3dsmax and never goti it to work properly. what is your workflow after modeling in archicad?
There's a new video for you:
Thanks again for the oportunity to share this with you. Planning to share some more "dune stuff" very soon...
