Zero-Room

Ignore the model, it took about 2 minutes and I toned down the reflection on the ball too much but I think it's more or less what you're after.

How I did it.
The white material:
Colour: 100% in all fields.
Reflection: 10% Brightness (the rest is default)
Specular: Width=50%, Height=700%, FallOff=-44%, Inner Width=0%

Apply that material to a sky and floor object.

I expect you have the right material for your object so I won't go into what I did for the ball material.

I didn't use any lights, just radiosity. (Make sure the autolight option is unchecked in the render settings)

Radiosity:
Strength: 100%
Accuracy: 63%
Prepass size: 1/1
Diffuse depth: 3
Samples: 300
Min Resolution: 16
Max Resolution: 18
Recompute: Always

You could probably play around with these settings to make a faster render.

Thanks for bringing my attention to this, it's a very nice way of showing off your models, I think I may use this in the future. :thumbsup:

Or do it the easy way: floor material with pure white material and render/compositing tag on floor object with "compositing background" checked.

But you don't get the reflection if you do it that way, or am I doing something wrong?

[AdamT]

You'd need to use an environment map to fake the reflection.

I mean on the floor. :)

Hello Phasmatis,

thanks a lot for your help !!
It is working very nice.
The radiosity takes a long time to render - i will work on this!

you wont get reflections if there's an area of pure white as reflections are additive (i.e. they just make the object brighter where the object being reflected is brighter than the object reflecting). so you will get reflections where there are shadows for the look of that room then it's better to actually make the wlals luminescent white, and the floor a slightly darker grey colour, but with a composting tag on it and highly reflective. you may also want to use the plugin distancefalloff to get the reflections to fade out.
