Hello. I've seen a few people talk about 3D waves in CityEngine,  however I've also seen about the waves being stormy and was wondering how to do it/what I'm doing wrong? 

Is there a way to change the parameters of the waves speed and height?  

I have attached the rule file that I have tried to use, Can someone please Help?

Hi @Cicada28 

Typically waves are done in game engine/ rendering programs like Unreal Engine, Unity, etc. using complex material/shader techniques.  The code you have shown is simply a 2D texture file (name).  CityEngine does not do animation or complex shading.   It is a procedural 3D content creation program.

If you are interested in making waves, start learning a game engine>  here is a interesting thing to learn for you:

Brian is correct. I do think though you can strategically tag generated materials for intake into those rendering systems/game engines in CityEngine. Material replacement is something that software like TwinMotion makes really easy if you can search by tag.

In addition to Brian and David, for advanced visualization you need to plan ahead and prepare/download materials in your game engine like Unreal Engine, and they you can reference those materials in CGA. It is little bit more involved but worth the effort.
