Is it possible to represent water in motion, a river for example?

Thank you 
Pedro Oliveira

Hi Pedro

Yes you can. There´s two options:

1. Choose one polygon and add to the end of the name " __water " : example myriver__water

A sample here http://bit.ly/2EWMpSR

2. Option two : Use the rule WaterMaterial.cga available on http://www.arcgis.com/home/item.html?id=067950a3a1f44129a10b3a458802e450

Hi there,

Could you allow us access to download the cga file? It says that we don't have permission to access.

Thank you sir!
