Perhaps you want to change on forest appearance in the game, Well as I said nobody knows where these .msh files (plate or as you say "plane")are yet, likewise no one knows where. msh files that builds up the clouds or draw roads and railways, or bid up the cube (the sky) are, so far these are undiscovered parts in the game.but I think it's the same plate (. msh) file that the game engine uses to build the entire landscape, but when it builds up the forest, it stacks same .msh file in 5 separate layers to simulate forest trees, and when the textures (wood0 to wood4) with alpha channel added to these 5 layers, forest is formed, which is one of the worst things in this game!
last year I used "PE Explorer" to look inside il2_core.dll and il2_corep4.dll to get some information and find where these file was hidden but not so much luck!!

There are information inside these .dll files which could be useful for someone who knows about dll files and dll programming who can break out them for more knowledge about the hidden parts of il2.
