Hi Fernando, Nice picture, really, I like the composition and framing. :) What do you mean about the attributes for the light? If you mean the brightness, on the right in the World Browser, you have options for "power", which is just like it says: the power of the light you have selected (point, spot or directional), and a box which can be checked or unckecked, to have the light cast shadows or not. Above that, is a box which is white by default, but double-clicking in it will bring up a color picker box, so you can get any light color you'd like. The "Sun" would be a different story and has more controls than the regular lights. If you click on the little sun icon at the top of the screen, it'll bring those additional options up. Note: The Sun and the directional lights cannot be adjusted for power for some reason, but moving them around, pointing them at the sky, ground, altitude, etc.... all have alot to do with the effects you can get. Hope this helps some, and if not, please ask some more. :) -Mike
