Can anyone help me understand how to create this wall-mounted waterfall in Blender? I want to animate it later. I've searched everywhere but couldn't find a tutorial explaining this.
There would be any number of ways to go about recreating something like this. It would largely depend on the end goal and possibly how powerful your computer is - if the water needs to be convincing versus absolutely photo-realistic.
It's possible to make reasonably convincing moving water using a texture on a plane. If the camera will not be close to the waterfall and the waterfall is not a major focal point of the scene then this could be the way to go.
If the camera will be close to the waterfall or the water, for some other reason, needs to be photo-realistic, then you'll probably be looking at fluid simulation.
Just a couple things to consider when working out the best way to approach a project like this.
One thing you could do is add a narrow plane along the top and make that a particle emitter. As particles you can use meta balls with a water shader. You'll need to play with the settings to find the look you're going for. In addition you can work with dynamic paint on the pool water to have it interact with the particles.
I did that a little while ago for a fountain and it looked more realistic than I expected - plus is less taxing on your hardware.
Thank you for responding. This seems like a good idea to me, but unfortunately, I have never worked with particles before. Do you know of any videos that can help me with this, please?
The CORE Fundamentals of Physics Chapter 5 and 6 deal with particles and dynamic paint respectively, there you'll learn all about every detail of it.
If you go about 39 minutes in you can see how I did my fountain with that system here: https://youtu.be/lO3TaLCzPRQ Like I say you'll have to adjust the settings until you find a look you like but the principle applies.
Yeah I'd also say to start with the Fundamentals, or even start from the Blender Basics, if you have never not only worked with particles or simulations before, but 3D in general. To jump into Blender and 3D without previous knowledge is usually very difficult, it's a lot of information to digest. You can follow a tutorial of what buttons to push and you may get things working, but problems will undoubtedly arise and if you don't really understand what you are doing, you wont be able to adapt, things will go wrong and you'll end up very frustrated.
I don't know if for that picture you posted you have to build the whole room or just the water. But again, my advice would be to build up your knowledge all the way from the start so when you reach the point where you're modeling and doing simulations, you have total control and know exactly what you are doing and you wont just be button pushing for the sake of it.
