View Full Version : Light Emitting Material?
cdinic 05-01-2002, 09:34 PM An old professor of mine is a Brazil fanatic. He once showed me how to build a material using an output map that would actually throw light. This was in Brazil, and I am using MR. Does anyone know if it is possible in MR, and if show what is the procedure?
I want a light emitting window. Check out an early render of the scene I am working on. http://www.chrisdinicolas.com/tub.jpg
Thanks for your time

Why not put a direct light behind the window and use that as a light source. With shadows turned on it would have just the same shape (and you can still use radiosity). In my experience 'real' lights give better and faster results then light emitting objects.
You have to build a wall though :)
(Or if that's the point, that you don't want a wall, then you'd build one and turn 'visible to camera' off in object properties, but still leave shadow casting on)

If you mean you want that white box in the window to be the object emitting light, then you have to bump up the incandescense (Spelled badly, I know) value, but I'm not sure if it's incandescense in MAX... it's that in Maya. But it's the value that controls how much the object is illuminating itself.

That would probably be called self-illumination in MAX. If it doesn't illuminates enough, put a white bitmap in the self -illumination map slot and crank up the RGB - offset / multiplier values in the last rollout.
You will probably also have to enable object based illumination somewhere (maybe object properties).

Thanks guys, I guess I'll have to find my old proffs e-mail address, or use Brazil... Thanks again
