Hey guys,
I've been showing off Terragen to some friends that have never used it before but have been mostly playing around with VUE. They are really blown away with how nice the sky model looks in Terragen and asked me if I knew what lighting model Terragen uses. They asked if it was Hosek Wilkie, but I didn't have the answer, so I thought I would ask someone here. From just looking around online, it looks like it might be, but I really have no idea.

Thanks, guys!


Hi Alex,

Terragen uses a proprietary atmosphere model. Mie and Rayleigh scattering are approximated in a way that allows some artistic freedom.
Just because milk is white doesn't mean that clouds are made of milk.


Ahh, OK.   Thanks for getting back Matt!  It is beautiful!
