Welcome to my third Tips and Tricks about Blender for Architecture.
It's about the use of bitmap textures for inserting trees and people in architectural visualisation.
I speak about the constraints too, to place the planes facing the camera, and to place a second plane for shadows. I explain the use of the add-on import images as planes too.
It's quite long, sorry for that, no patience to do it again shorter.
Hope you enjoy it.
