Tradivoro, it's funny you should mention that way to fix it - I came up with the same fix myself. I was originally about to ship my b5 trees and then I noticed this problem. My eye for quality told me I wouldn't ship my trees in the store until I found a fix and I did. Enclosed are before and after images showing the fix on one of my pine trees - the Giant Sequoia. The trees should be available for purchase in the Renderosity store within the week. I've been working on these 10 trees for weeks now and they contain custom DTE textures that match the real tree bark. Unlike the 'presets' that ship with b5, these trees match the real ones for bark, colors, scale, shape, and texture. Let me know what you think.
btw - I also like and use Digarts trees for Painter. They make excellent background trees. B5 trees make excellent trees you can put right up to the camera.
