Slim, you are right. The trees are not procedurally generated, and neither is the terrain. The trees are not simply placed randomly. They are placed, but take into account the position relative to other important features and the slope of the terrain. Without doing this, you often get trees placed on ridiculous slopes, where the underside of the tree can be seen. Obviously they also have randomised pan and size.
Bluebeast – Sorry about the post. I have tried to fix it, but I don’t seem to have the same problem as you on my display.
You will be please to know that I have also change the terrain, tree and object materials so that they work together in how they are shaded.
I have looked into shadows for the forest, but I can not find any soft shadows shaders which can be implemented into a c-script script. As this is the case, I really can’t use stencil shadows due to the issue they cause when the camera moves into them.
Thanks for the feedback everyone.
