I've posted the screens showing that the tex bark 05 does look a lot better on fir trees and maps like hattert already have been using them in the skins tab inside static properties as well as bark 03 for the pine trees and it's not right that they were using the same bark tex as the winter ones (it's why they look so bright on san valentino map) ^^bark_03 ^^too bright ^^bark_05 a lot better as the other one that is too bright is meant to be for winter maps.
