@Rondi: Ill think about a video once ive completed the file-package for you. About the water: Well, Shade-C (beta) water is stil wip. The Part in the middle of the water is GS watermirror shader.
About vegetation: that is why i stil wait to fill the level with grass. I wanna find a solution that has almost no effect on the performance. The Methode you suggested about using one big file for grass is one idea, but i would prefer to have a colormap where the grass models generate themself if the player is near. The Serious vegetation code is almost perfect for that, problem there is that even the invisible grassmodels are stil sucking on the performance.
