Opacity Maps Optimization

[lizGYM66]

Apart from making actual geo, are there any ways to optimize the use of opacity maps when it comes to things like lots of trees and grass? In Redshift there is a sprite node to replace the regular opacity slot.

There is also the ray_switch shader.

Thanks @lee_griggs . I looked up ray switch (your link doesn’t work). How would this be utilized in this case?

How did you get on? Was the tutorial helpful (even though it is Maya)?
