Hi guys. I am making a map in Hammer that will be a Control Point map. The thing is I want to include a stream that flows into a waterfall. I have a few questions about this. 1.) This is probably a stupid question, but how do I make water? 2.) Once I've made the water, how do I make it look like it's flowing in a certain direction? 3.) Is it possible to make it so that when someone falls into the water they get carried away by the current? 4.) Is it possible to make a waterfall in Hammer? If so, how would I make it look good?
