Easiest way to create rays from sky? (God rays ? )

Unity Engine
1

I have Unity Free, and I have a forest with lush foliage and nice trees. But it’s a little dark, and I noticed that the shadows are making things a little dark. Any way, how do I make so there would be beams of light going through the trees, I think they were called God Rays? I am not sure how to achieve this without Unity Pro, I don’t have $1,500!

make planes in 3d space with gadient alpha maps to fake them or buy pro and do it with post fx.

Bump, is there a more realistic way to do this without getting Unity Pro? Because I do not have $1,500

No.

The new Standard Assets beta contains god rays that I believe work with Unity Free:
