Ah ha! No wonder... yep, you can't have a devoid area (totally black is
pretty bad) or it too will be included in the radiosity calculation.
Sorry about the typo, I meant 0.015 not 0.15 was minimum_reuse default,
thanks for catching that.
You may also have to use a higher assumed_gamma together with very high
ambience. That way you get a more luminous radiosity while keeping the
overall brightness down. Wish the 'brightness' keyword did this.
