Howdy... new here, and this forum looks like a good place to be. Anyway, I've been playing with the demo (which ran great from the get-go with no tweaking, turning off extensions, etc... G3 yosemite, 700 something ram...) So - is there a way to create frosted glass through which light diffuses accurately? Or at least somewhat accurately? I'm guessing with caustics there is some way to do this. Any thoughts? Thanks! Andrew
