GRASS and WATER material in vertical wall

Vertical grass or water is not (yet) supported - Depending on the scene/project of yours you may want to use some of our bushes which you find in the Asset Library which may be able to replace any vertical grass you wanted to see rendered.

May I ask why you would like to use either vertical water or grass? Perhaps I'm able to give you any further tips/tricks. Thanks!

goncalo.t3 , it may not be an ideal direct solution, but you can use the following "Bushes", rather Grass Assets for a Grass Wall:

SketchUp in combination with Enscape also allows you to resize the Assets at hand in whichever way you like. You can even overlap some of those Assets into each other if you wish to have more dense Grass. Just work and experiment with it a bit until you're hopefully satisfied with the results!

When it comes to a waterfall itself, you could use an animated texture potentially depending on the scene of an actual waterfall to at least create the illusion of it (You may very likely have to use only a section though if you can't find a video of just a waterfall cut out) - Generally though, I am unfortunately not aware of any special techniques to create a natural-looking waterfall. Still, feel more than free to forward this as a request through our portal so that our Product Managers can track the further demand!
