This is really good, having presets is nice but an companion tutorial on how it works makes it even better and I really think it's a good idea to have them both as separate products (even if I already know I will buy both. They are things, I just cannot resist and after seeing the renders you made and knowing it will actually give the same result with my renders (seldom happen because I do stick to the real world size). I'm already addicted to QuadSpinners product, I love Terrascape, I think I will love your products too.
