Load trees and grass in a certain radius of the player only

Hello there.

I have been wondering for quite some time now, on how to load grass/plants/trees in a certain radius of the player. My map has high fog density, so I don’t need the player to see trees nor grass/plants in a radius greater than 20yards or so.

How do I achieve wanted effect?

funny you mention radius, The easiest way I could think of doing this would be with make a sphere detect trees and turn on their renderers, SIMPLE (in theory)
