Hey peeps,

At the moment i'm trying to create the following.

A white plane that serves as a 'ground'
and a red area light that casts red light across the ground.

How can i make the plane as white as possible and still be able to cast light over it ??

haha.... i'm suprised to ask this as i thought i could've figure it out myself ;)

anyway..... anyone with the solution ?? :) thanks thanks thanks

I'm not sure what you're opting for, but if you ant the plane to have a crisp white color, even if light isn't really shining on it try bringing up the ambience instead of color...

Not sure this is what you asked for...

correct me if i am wrong.. but you try to create a red light on a 100% white plane?

that sounds a bit to me like switching off a broken light in a pitch black hole - it has no effect.

since you have a bright white surface and you ADD light to it, you will only get a whiter white ;)

how bout this:
subtract light from it?
(so the surface has 100% incandescence white and the light the following color:
r 0
g -1
b -1

like that you will get the red light on the bright surface (if that really is, what you want)

cheers

you are right chappo, in case you want a 255,255,255 white in the rendering.

but if you want 2 achive an object to appear white in the final rendering, you will become always a look! of grey instead of a white,... so it´s need to reduce the light absorption by increasing the diffuse level ! to get rid of mayas grey smear
