So today i have been working on multiple things, the main one being the moss on the tree. Olly showed me that by using a mask and a displacement map in photoshop that i can easily apply the texture to certain areas of the image. It only affects the areas of the displacement map that are black which left me which moss in the deeper areas of the bark. It is a quick and effective way of getting around what would have been a tedious job.
This is a quick simple texture of the tree with the moss applied, it makes it look a lot better and a bit more realistic.
