Hello All. My First time posting anything here and hope I'll post some more, sometime later but for now the info.
So I made this thinking of a nice warm island-ish sunset. I don't think it can compete with some of those HIGH stuff people make around here but I'd like to consider myself a well enough learned person in Terragen ;D although I CAN USE SOME MORE TRAINING 4 SURE :D
Using Terragen 2 on an AMD X4 at 3.2GHz this one took me an hour to render at 1600 x 1200 :( (btw anyone can give any hints on how to reduce that NOISE GRAINY effect on the mountains?)
You could probably get rid of the noise by raising your atmosphere samples and\or raytracing the atmosphere. I would try the raytracing first, raising the atmo samples will slow your render down.
As Yossam said... more Atmo samples, and maybe increase AA... love the atmo, by the way :)
