Tutorial for Creating a Waterfall in Unity 

Step 1 – Create an empty Game Object. 

Step 2 – Rename the empty Game Object as “Waterfall” and scale the Y-axis position to 100 from Inspector Menu> Transform > Position. 

Step 3 - Add a 3D object plane and rename it as “Water Surface” and scale the X, Y and Z axes to 25, 5 and 25 respectively. 

Step 4 – Add a material folder to Assets to store the materials to be used in making the waterfall. 

Step 5 – Make the “Waterfall” object as the parent object, while making a new “Particle System” effect as its child object (Effects > Particle System). 

Step 6 – Select “Particle System” and under <span class="NormalTextRun SCXW48185591 BCX0" <inspector <="" span=""></span>Inspector> Particle System, do the changes as shown in the image below. 

Step 7 – Right Click under Project Menu > Create > Material (Name it “water”). 

Step 8 – Download the image of water from any source then import it in Unity > Assets > Materials.  Select the “Water” material, then drag the imported image of water under Inspector > Main Maps – Albedo. 

Step 9 – Inspector > Shader > search “Additive (Soft)”.

Step 10 - Select “Particle System” and add the newly created material - “Water” under Inspector> Particle System – Renderer. 

Step 11 – Right click on “Particle System” > Duplicate and rename it as “ParticleSystemDust”. 

Step 12 – Select “ParticleSystemDust” and under Inspector> Particle System, do the changes as shown in the image below.

Step 13 – Right click on “Particle System” > Duplicate and rename it as “PSWaves ”. 

Step 14 – Select “PSWaves” and under Inspector> Particle System, do the changes as shown in the image below. 

Step 15 – Right click on “Particle System” > Duplicate and rename it as “PSWavesSprinkles ”. 

Step 16 – Select “PSWavesSprinkles” and under Inspector> Particle System, do the changes as shown in the image below. 

Final Preview 

Nice this is really useful!

TBH, it looks more like Old Faithful at Yellowstone than a waterfall. Where's the source of the water coming from? Water doesn't just condense in midair and then deluge down in a waterfall. I think you're imagining rain but with the viscosity of a river. If that ever happened IRL we would probably have colonized Mars centuries ago as such conditions on the Earth would be dire & unacceptable for a home-world. :-D Just kidding. ;-)
