Gilles sent me his scene files, and I've also tried adding trees to a blank scene, changed the sun position, changed the viewpoint, selected a tree, moved it around, gone back to the first step again, varied the order in which I did these things and so on.

Remko, can you also check this out when you're back in the office tomorrow morning please?
