Have realtime light cast shadows on terrain only, not trees and details.

Hi guys,

I’ve managed to bake my terrain trees and details on to a lightmap, so to try and save on the frame rate, I wish to use a realtime light that will only affect the terrain (without trees and details) and characters standing on the terrain.

I got as far as understanding I can put all these things on a layer so other stuff is not influenced by the realtime light, but how do I stop terrain trees and details casting realtime shadows?

I did it by adding a ForceNoShadowCasting tag to the Nature shaders.
