Anyway sawman
the floating trees your seeing are not due to a bug, its how they are meant to be.
The same tree cover can be seen in IL-2 FB, its basically multiple layers to give the impression of depth and hence a forrest look from the air.
Now this works fine in IL-2 as there is no time in the game normally where aplayer would find himself parked up next to the forrest, but in AH the is.
heres the problem, you've heard of polygons? they are the building blocks of the computer world and consist of triangles, 1 triangle = 1 poly so you'll notice that some of the tree are simply made up of 2 flat planes with a texture on in an X shape so that they appear to have substance from any angle you look at them.
these simple tree will take 4 polygons to make. so to make a forrest of them will take many hundered of polygons, and equal slower frame rate for the player.
to solve this you can make the computer draw only what is needed so when flying a certain distance from the ground the trees will dissapear and you frame rate will be better, as in AH1 (although even in AH1 the trees became clutter so are able to be switched off).
problems with this is if a gv is hiding under a tree the tree has to appear to be there at all times to all players, so it cannot be made up of many polygons, so the floating trees you see at the moment are an attempt at very low resourse hugging persistant trees, to provide cover for GV's.
thanks
