I know I'm in the middle of the bar scene right now, but an art test came up, and I need to come up with a cool forest maquette by Wednesday. I've been making some trees and materials for them. Here's the reference;
Here are the bark & moss material I've created so far. The moss material has opacity so the bark will show through at certain areas.
And the trees;
Biggest issue I'm having so far; The materials look pretty bad close up due to the trees being so big. Of course, I've got the UVs repeating 20ish times, and I'm using 2k maps.
