Particle animation on a path

Is it possible for particles to follow a path? If so, which spline package should be installed for this?

Hi, do you have an example of how this should look like? Do you mean the whole system should follow a path or individual particles?

That’s my theme. Many points flow quickly, fewer points flow slowly. I think you recommend me to animate the emitter, right? But I wouldn’t animate the emitter but just assign a path to the particles.

I see, that’s currently not possible out of the box right now (I think you can’t even do that with Unity’s default particlesystem). Have you considered using a texture to visualize flowing gas/water like this?

You could create a custom script probably but I havent tested this and am not sure if our current api allows for that

The texture animation works very well with your shader. Was able to represent flow velocity and temperature very well. But it can’t be seen in VR. Ok, I’ll try to animate the emitter.

Actually, that’s how it works. With animated emitter. See you soon and best regards Matthias
