Noted.  Unfortunately, alpha transparency is a nightmare -- only
things drawn *before* the object with transparency will show through.
I draw the dynamically-placed objects after the ground, so you can
always see the ground through them, but they are drawn before the
clouds in the sky (since you will want to see them through the gaps in
the clouds).  It will be (apparently) random whether any individual
tree shows up through the alpha portion of any other individual
tree's texture.  I know of no appropriate solution for this problem.
The current arrangement works best for the normal situation, flying
above 100ft AGL, but you're right that it can cause problems when
you're buzzing cows.


All the best,


David
