This is a waterfall made from two terrains. I oriented the flow in the Z direction Applied the preset deep blue water texture created a 15 frame segment Went to the 15th frame and set the Z offset to 20bu Created a keyframe. Went back to the zero keyframe and set the offset to zero. (it had also changed to 20 because I had not set the initial keyframe) Created a Zero Keyframe. The resulting bitmap sequence was combined in jasc animation master to create the GIF you see. It had to be reduced to 63 colorsand small size to post.
