• How to create this effect on PlayCanvas

Hi @chuxinhao,

Real fluid effects are something quite heavy for most rendering engines, apart from tech demos.

The closest you can come is using either a particles system or an animated texture.

Here is a waterfall example of the latter:

Stylized Waterfall Shader - Free and tutorial link

Hello, Today I saw an Godot engine tutorial about creating waterfall shader. I made in PlayCanvas and decided to share it freely. (It also contains some model to make it better) You can find more on Harry Alisavakis And here is tutorial about shaders : http://halisavakis.com/my-take-on-shaders-unlit-waterfall-part-1/ Here is the project link in case you want to clone or use it : https://playcanvas.com/project/687182/overview/waterfall Here is Youtube video : [Screen Shot 2020-05-16 at …

@chuxinhao

Are there any examples of implementations using particle systems?

Sorry, I don’t have any in mind.

I think it is too performance-costly to simulate it in realtime.
But you can try to simulate your liquid in some 3d-modeling software (Blender, Maya) and export it as a mesh. You will get a mesh and a bunch of blend shapes representing the “shape” of your mesh at each frame. Then you just need to animate through each of your frames.
I never try it, but if you have no other choice, it is worth to make an experiment.
