ok, reloading skin helped me to get this far
the tree u see is with extra alpha layer (black 50%) and there is another one invisible without extra layer, just RGB
still doesn work
basicly what happens is, it removes few spots of my tree, wich isnt black actually and leaves stays untouched.. there is 2 tga pictures merged together, but now after reloading skin its one, but still doestn work



and this is look from my photoshop, as you can see, black is at 0,0,0 0,0,0
