I had someone ask me “How do I do a water wall in 3D?”, and it got me thinking. There is no “right way” in 3D, and there is always more than one way to skin a rendering. It’s all smoke and mirrors anyway. The two water walls in the rendering below were achieved with two different techniques.

The wall on the left has a plane “draped” over the wall with a combination of a wave and bend modifier. The wave modifier creates the ripples in the water going down the wall. The bend modifier bends the plane to follow the curve of the walls. Be sure the plane has enough segments in both directions for the modifiers to work correctly. For this example my plane was segmented at 100×100.

For the wall on the right I created material (using the A&D shader) that mimics flowing water going down the wall. This is achieved with a noise map in the bump slot. The trick is to increase the tiling of the noise map in either the X, Y, or Z direction. In this example, I cranked Y up to 40. This will create the effect of water running down the wall. Also be sure that the material is highly reflective to look wet.

My preference is to create the water through a material and apply it to the object. I find it much easier to control. If you want to check the file out here it is:
