Deep Forest

Here is a pretty big update. I reworked my tree models a bit as well as added a bush model. I'll add more ground plants as I go. I fixed my water shader so it now gets clearer as it hits the ground. I've made changes to my post processing and completely fixed my shadow problems. Right now I'm just playing with the deeper darker forest. I know I will have some elements of that in the final but it will be a bit lighter as I vary my tree sizes.
