Does anyone know any good tips to make a convincing animated waterfall? I tried particles, but um…not good. and Fluid sim…be a bit hard?

Couldn’t you have an inflow in side a box with one side missing in order to aim the inflow.

Hi !
You can do a lot with only animated texture.
In this movie, I have used transparent materials with stretched clouds textures set to Spec and Disp in the Map To panel, and also the wave effect for the water in the lower part.
It is less consuming in computer ressource than particles or fluid, and you can achieve good effects if the camera is not too close to the water.
