There are some artifact when using bounding method +b2 with the current beta
12a version. Also it seems that fog gives quite different result in the
scene. Maybe it is intentional redesign of this feature, I don't know.
// the definition of fog in the scene
fog {
fog_type 2
distance 50000
color rgbt <0.8,0.9,1.0,0.0>
fog_offset 300
fog_alt 900
}
"Square" artifacts appear in the shadows of the trees. They are created with
MeshTree macro by Paul T. Dawson.
