For anything but a very pointy coniferous tree, that would mean extending the triangle fairly high above the top of the tree, which would lead to one current problem and one future problem: 1. Alpha textures cause all kinds of ordering problems; if the alpha texture sticks up higher, it's more likely to obscure some sky. 2. If we ever implement collision detection for these, you'd get a collision even when you were well clear. That said, feel free to experiment -- everything is configured in the XML, so it's easy to play with models, densities, etc. All the best, David -- David Megginson, [EMAIL PROTECTED], http://www.megginson.com/ _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
