Hello all,

I am trying to visualize a bright white room with a timber flooring. The problem is that the floor bounces too much light so that the walls and the ceiling have nearly the same color as the floor.

So my question is: how can I avoid the coloring on the walls?

Thank you very much

Yes, the intense bleeding might be a scale issue, however, it would be nice if you could post some images. In reality, most things, what your eyes see white, aren't white at all.
I don't know if maxwell has an automatic white balance controll (I dont think so), but maybe, you can use some external softwer, that is used to post adjust the white balance of photos for example.

A photoshop "auto color" correction might be the simplest way to solve this (if it isn't a scale problem).. also, pure diffuse reflects colorfull (red) light but if you use specularity and roughness, the bleeding should be less important because balanced by the "un-floor-colored" caustics coming from the floor..

Anyway just ideas!

Check the colour of your emitter as well. I had done something similar using "Cool White", but turns out it's got quite a yellow component. Try D65 or go custom.

Thank you very much for your help. I really appreciate it.

Scale doesn't seem to make a difference. Here are two images to compare:



First one with a marble texture for the floor, second one with a timber flooring.

I have used only sunlight, no emitters. So what the hell am I doing wrong?

Looks like your scene scale is wrong...if you're using max can you upload the scene, no need to include textures.

Or look in the tutorials section, faq thread.

I don't think the scale is wrong. I have tried the scene with a scale factor of 10 and there is no difference. Maybe a LightWave thing.

I think you should increase the specularity of your floor. Odd, but the last image seems OK to me, because the floor looks like a rough, diffuse plane.

Three more tests. I found an acceptable solution. The scene needs more direct lighting.



On the other hand - in real life it looks more like the last image. Without an extra light source

Yeah, "cool white" is a total misnomer. That should be changed before release.

Actually, in the lighting trade "cool white" is a yellow/orange white. When I first encountered it, I too thought that a cool white would relate more to a colder (i.e bluer) colour. In fact it refers to the colour temperature of the light. 5500 Kelvin being "cooler" than 6500K.

So the term is correct with respect to lighting conventions and so I think it should stay.
