Hi & thanks for the great tutorial, helped me out a bunch!
maybe a stupid question but here goes
Why do you do the last part, the overlay effect? You say this is the most difficult part, but i don't see why it's necessary.
If you just save that forest to a png file, you could use it as a parallax, no?
The answer might be obvious, but i just don't see the necessity of the last part.
Tnx in advance
