Mapping problem

[angrysully]

I needed to ask something about my map. It has a water fall in the map and i dont really know how to do it correctly. I made the water fall part a func_converyor but when i look at it in game its invisable and also, whats a good number for water so i can see though it good but its not like glass

additive render (rendermode 5) about 200 opacity (renderamt 200) make sure the texture starts with "scroll" or it, well, won't.
