It looks like your water misses some textures needed for the shader or something. Perhaps the shader needs a model with two textures, one colormap and one bumpmap? Which shader are you using?
Did you include everything that's necessary? For example did you include:
Code:
bind "default.fx";
Can you post the entire code you are using? It must be something related to your code ór to your water model, since it did work with the example..
Cheers
