Hi folks,

The following - or something along those lines - needs to be woven into 
the Radiosity reference documentation on the Wiki 
(http://wiki.povray.org/content/Reference:Radiosity); in addition, it 
might be worth mentioning in the what's-new section:

--------------------- Syntax:

(The syntax needs to be extended to include another setting, 
`brilliance`, which takes a boolean parameter, i.e. `on` or `off`.)

--------------------- Description:

By default, radiosity computations presume that the texture to render 
has a `brilliance` setting of 1. In scenes that make heavy use of 
radiosity, this may cause surfaces to look excessively dull.

As of POV-Ray v3.8, you can force radiosity to respect the `brilliance` 
finish parameter, by specifying `brilliance on` in the radiosity block. 
Note however that this comes at a cost of rendering speed, especially 
when combining surfaces with various different `brilliance` settings in 
close proximity.
