When I create 2D sectional drawings of buildings I find that the background which comprises semi transparent 3D trees and a distant semi transparent tree belt circle do not render properly in sketchup pro 16. The most distant tree belt ‘grins through’ the trees in the foreground destroying the impression of depth that I am trying to create. Use of fog between the 2 planes does not seem to help either. Is this a rendering issue beyond SU or something I can improve within the programme? Any comments on this would be greatly appreciated.
