I am making an underground lake, fed by a waterfall. This lake then drains into a river with a gentle current leading out of it. Well, I got the waterfall built quite nicely...it is not just a scrolling surface, but a 3-d waterfall you can move in and out of. I got the vectors for it's surfaces calculated and put in just fine. It works and looks how I want it to. The problem I am having is with the lake. I used 2 ghost things to calculate the vector, just like the waterfall surfaces. The problem is the surface scrolls sideways realative to the direction I want it to appear to drain. Also, the river is straight in line with the lake vector, so I used the same one there (adding those surfaces to the cog). Now, the river almost works right. It runs in the line I set, just 180 degrees around. So the whole effect is of a lake surface moving to one side, and the river draining back into it instead of away from it. I do not understand how the same vector used in surfaces in a straight line would do this. I thought the darn water fall would be hard, but the "simple" part has me stumped. I have used the same technique and gotten wierd results. Any one have any insights into this? Any help is as allways greatly appreciated!
