Hi Greg,

> The larger sun that includes circumsolar will lead to slightly enlarged penumbras in some cases, but it's a reasonable compromise.

I thought that (with default settings) a single ray is used to sample a "light" source solid angle, resulting in no solar penumbra.  Has this changed and/or am I misunderstanding this?

Cheers

John
