Hi guys!
I’m new and i check often in this forum tryng to solve my problems…
now i had to post a question…
I do interior designs and from few months i start using vray for sketchup but now i had to do my first exterior and the problem is:
HOW CAN I RENDER TREES?
can i assign an alpha channel to a cutout tree on a plan like i used to do in previous software?(and if so, someone please can light my way? ???)
and if not there is another way, avoiding to insert 3d plants? i can’t even place them!!
here there’s one of the images,

Re: trees and alpha channel

Make a grayscale clipmap from your diffuse bitmap in a photo editing program and load that into the the “Transparency” slot in the VfSU Texture Editor.
