Material rendered differently depending on other Material used

Rendering Flamingo
1

Hi

I am using Rhino 4, just installed Flamingo nXt and did some test renderings. What confuses me is the following:
I have some surfaces (lying flat on the ground plane) and assigned some material to it (olive green plastic). Then I rendered the surfaces using the Top viewport. The result looks like this:

Now I changed the material of the first “e” to something else (gold coloured plastic) and rerendered the picture. What I do not understand is, why Flamingo renders the other surfaces (which still have the same material as in the first render) differently. Now the rendered picture looks like this:

What am I doing wrong? I do not want to always have to change the material by trial and error depending on what materials are used in the scene. Any help is greatly appreciated.

Thanks

Flamingo adjusts the exposure to the scene.
