3D Environments in Blender Udemy
These are the results of the second environments course that I took.
These scenes are very detailed. You actually learn to make grass and trees as well as buildings, rocks and rivers. I was really impressed by the "Real Snow" add-on (snow on the trees especially) and the "Ivy Generator" (on the cabin).Highly recommend this course for any Blender user who wants to make detailed large scale landscapes.
