very nicely done. I'm thinking of buying Terragen 4 as I'd love to create images as spectacular as this. I'd be using a render farm though as I don't want to have to wait hour & hours for the render to be completed.
Well, my workflow goes like this when i have a day off to use in terragen : Create the image fully in 3-10 hours. Do something else until you need to go to bed and just before you go, start the terragen render for your image. That way you have a fresh new render waiting for you in the morning most likely !
Yap, planet + terrain made in terragen Glad you like it my friend !! And everyone can learn to make em ! Takes little time and focus. But if u put ur mind to it, wont take long till you start rendering pics like this [I've been playing around with terragen for 5-7 years now.]
