Hi everyone.

In the image above I used 225 ranged spotlights to achieve the illuminations I wanted. Plus, I used blurry reflections instead of TrueAmbience to fake radiosity. The areas you see circled are not directly lit by any spot, and get their hue from blurry reflections.

This time there's not enough material to write an article about it, but I nevertheless thought to show you. I followed the tut at bsolutions (link above), tweaked a lot around with the ranged falloff of the spotlights and the blurry reflection value of the various materials (is driven by the grey value of the specular halo) until I was satisfied. Basically, the formula is to make the diffuse and reflection values sum up to 100, more or less.

It's not mangificent, but I still think it's better than TrueAmbience renders. Sorry for the high compression and hard resizing. You can see a higher res version in my gallery.

Good Sunday to all!

Stefano

Yeah i use this method for all my radisoity. In some scenes I use blurry reflections and true ambience, but usually I'll use one or the other. The skating wheels above were rendered using a daylight setup I have created. It uses 15 lights (no soft shadows) and blurry reflections.

I have to try this! Thanks, DC!
