Wanted to add a requested feature. I've been drooling over the water shaders but am a dummy as far as programming. I was thinking if your editor could be set up to show a terrain (for the river bed or ocean floor etc) and water over it with shader, then allow me to click and browse to try different textures for the water, environment, bump, terrain etc I can create some nice sets of water textures with matching sea/river bottom etc for the community. Right now I'd probably edit the code to change textures etc and truthfully I've mainly stayed focused on texture and level design. If I could open PSP in one window, try some textures in the water editor and see how they look, make changes in PSP and then load up the new texture set to instantly see I'm pretty sure I can contribute significantly better textures will look great with the water shader.
