How to modelize a water surface in CityEngine ?
Generally in the model view, people apply a texture to a surface with a bump map. Just Google water bump map textures and lots of general options appear. You can apply a bump map somewhat like a normal texture, see help link below.
More information on bump maps:
Bump mapping - Wikipedia, the free encyclopedia
For web scenes we have an active water rule, while you might need another jpg, the general code is attached.
I hope this helps.
Thanks for the information !
