I have a suggestion though: in addition to providing a Project Folder download at the beginning of each lesson, you should also provide just an asset package so that people who are creating their own unique island can continue working with their original creation.
Thanks!
Oh, and a question that I wanted to post in the comments section of Lesson 2 Part 6:
Why does the light (pre cull mask) hit the inside of the house; why doesn’t the roof and other walls block the light? By culling the whole house doesn’t that remove the nice lighting on the outside of the house? And how about a cast shadow of the house on the terrain?
