Hello folk!
Sorry for the stupid question, I’m a newbie.
Can someone show me an approach how to make a pipe with animated liquid stream?
I got tube - it was easy, but Google didn’t help me with liquid streams examples.
It seems like this example is more close to my case Babylon.js Playground
Hello and welcome to the Babylon community!
The example you showed is using Particle Systems Particles | Babylon.js Documentation (babylonjs.com), so you could play with properties like the emitters, direction and speed to create an effect of flowing through a tube: Babylon.js Playground (babylonjs.com). @mawa also went in some great detail about this effect in a recent post: Make diffuseTexture move over mesh - Questions - Babylon.js (babylonjs.com)
Hum, I don’t remember having done that (I only did some fluid rendering demos but that are not relevant for this thread)…
Maybe a picture of what you want from google search could help? Are you thinking like a faucet with water coming out, such as a sink or coffee maker? Or like a top down view of an oil pipe that is kind of see through that so that you could see the liquid
If it really is a pipe, I wouldn’t do it with particles. Either simply animate a material or create a node material. If the pipe is only horizontal (does not go up or down) and you want to show a flow that’s filling just half of the pipe and/or is eventually an irregular flow, you can create a half pipe inside the pipe and then animate this mesh material (or as I said use a node material).
Oh I just remembered I have a waterfall NME example here Waterfall | Babylon.js Playground (babylonjs.com) 
If that’s what they are looking for I got an example too!
Piped water?
