oh and BTW. The HDRI stuff can be a bit confusing at first. (At least it was to me.) There are actual HDRI formatted images, that are made through a process of exposure ect. Two links here that I found while reading up on it. http://positron.cs.berkeley.edu/~gwlarson/pixformat/index.html http://graphics3.isi.edu/~debevec/Probes/ These tend to output a slight better output that using regular .jpgs and the such. But the two images in my previous post were done just by using a normal .jpg image with the Image Filter> HDR Expose That way you can turn Bryce images, or anything into a IBL source. Here is a second method completely, that was on Newteks site for producing the Global Illumination effect of Messiah:Render. http://www.users.space.net.au/%7Ephaedrus/phaedrus/radiosity.html You see LW can also do, object based lighting with its radiosity. For example, you set a ball over a box in a scene with no lights on ( turn off "affect difuse" and "affect specular"). Set the Balls Luminosity at say 300% (type it in, the slider won't let you go over 100%) and then render with global illumination on. The ball will cast light of its own. Put a texture on the ball, and it will cast light with colors based on the texture. Opens the door for real TV picture in a dark room, glowing signs, fancy light fixtures ect. Hope stuff wasn't too basic.. it kinda impressed me when I first got LW. ML
