Ever happened to you? You're modeling something, experimenting lighting and textures, you don't have a goal, a complete set and suddendly... poof here comes a render. Sometimes is something completely alien from your original thoughts. Well, this image is just that.

I was testing lighting conditions for the anim of my fantasy plane (this one) (http://www.cgtalk.com/showthread.php?threadid=125122) .
The scene is over the sea, and planes are following one each other just between the waves. And here I am, testing different solutions to get a convincing ocean. I have a plane (512x512) an animated displacement map and a two spheres to check reflection over the water. I decided to give the lights a try, to test the water material effectively and so I begun adding two direct lights. Results were not convincing and so I decided to change the material from water to another one, just to see what was the problem. And the image you see is the result (I only added a few stones in foreground)

Everything is modeled. They're just displaced polygons over the plane, as described. (in the anim they're waves and are animated... with proper texture they do resemble waves.. I was surprised to see that with another texture they indeed seemed like dunes)

Anacardo, listen, if you add a volume light simulating the sunrays penetratin through the clouds and proyecting in the ground lighty points, mmm my idea is some like Biblic landscapes pictures.
This effect can give to scene some personality and do it more strong. imho. :beer:

you sure have a point. I love volume lights and try to use them anywere seems appropriate. The fact is however, that I really didn't want to create an image, rather showing what happened by just changing a material during some testing. The image itself is not much, I know, what i tried to communicate is the surprise I had. Just as the image wasn't mine at all. This is why I didn't modify the image too much (as I said, only added the stones) and tried to retain the 'feeling' I had as fresh as possible. As for volume lights, be sure!! ;) there will be plenty of them in the sea animation I'm working on... Thanks for the advices (and the nice images too!).. Talking of volume lights... look what I found in my lost portfolio... sniff http://www.edelrolandi.com/cgchannel/cargo.jpg the quality is damn low, but it is the only image I have of this spaceship... this is archeology sniff.. done on a PowerMac 120Mhz in old 1998... oh dear... sniff... I used stratastudioPro which was the first program on the mac to fullt adopt volume lights. The image is an unretouched frame of an old anim.. which I still have... but oddly enough, don't have the codec (nor the mac) to watch it again...
