Roflmao I actually have World Builder.. and don't use it ;) What I meant by real was that even if a tree is far away the raytracer takes into account its Z-Depth, light tracing and so forth.I use the Z-Depth render to do Depth-of-field in Paint Shop Pro. If you use an alpha plane it doesn't have Z-Depth (well flat) and for some stinking reason my alpha plane trees are always too dark. But yes I agree, for far off trees alpha planes can't hurt, I just have not found a convincing way to use them.
