Does anyone have a suggestion for the following: I am making a rendering for a showroom and we want to show the client several ceiling options. One we want to show him is a plain white gyp board ceiling. How would you light it so that you get a nice and constant white?
Depends on the quality you are looking for. I assume you are skipping anything like GI (not sure what VW has).
If it is just for a general idea, what AntiSt said. Don't be shy of using a ton, soft shadows will render very quickly.
Judging by your scale, I'd start with about 20-30 of them, very, very low intensity, make sure that the attenuation is at least as wide as the room. make sure the shadows are extremely soft, almost invisible.
That's give it the soft look of GI and reality.
If you want a simpler approach, take a direct light (not a cone or omni), have it exclude everything but the ceiling, make sure that it is much wider than the ceiling. That'll light the entire ceiling evenly, just won't look realistic ('cause nothing in reality is perfectly lit).
oh, yeah, real cheat way is to make a self illuminated material, make it glow a little and it will look white and even (what bollocks is saying, I think)

Rendering Lighting Advice

Drop an Omni light in the middle of the showroom using 3d max?
Nope, VectorWorks 2008.
I guess that would be called a point light in my application.
Would you give the ceiling some sort of reflectivity?
Doesn't quite come out right
use lots of soft shadow lights in the places they would actually be and send in a nice strong sun to do radiosity into the space.
IED files are available from most light mfgs to get accurate lighting

also create a white texture for the ceiling
Thanks for the advice. I am playing with it. Right now I am at too bright.
if you post process it and take down the white side of Levels does it look ok?
