Something I worked on for ACV: Dawn of Ragnarok - golden leafed trees and grass with golden tips.
The main challenge here was to create a golden metallic shader, that combines well with the existing vegetation pipeline for Assassins Creed, as this was entirely missing as there are no metallic foliage in nature.
There was some fiddling with the textures to get the proper effect and not just have the leaves be yellow.
