[RELEASED] Fluid Dynamics : 2D GPU Particle System Fluid Simulation.

Fluid Dynamics is a 2D GPU Particle System Fluid Simulation for Unity. Fire, smoke or any other fluid in your game in realtime using GPU.

Fluid Dynamics uses Compute Shaders and PC, Linux, Android compatible, but please make additional check here

itch.io - https://seedo.itch.io/fluid-dynamics
Asset Store - https://assetstore.unity.com/packages/slug/137435

Features:

PC and mobile friendly
Full source code included
Vorticity control
Viscosity control
Multiple simulation spaces support
Full control of physical based simulation
Fluid flow followers support included
Multiple Emitteres
PC and mobile controls support (included)

Four example scenes and online documentation included.

 

Finally released in Asset Store - https://assetstore.unity.com/packages/slug/137435

 

There is no demo on itch.io page.

 

Sorry about that. Demo projects now added.

 

Just bought and imported the asset today. You might want to include some project setup instructions other than the prefab/component usage. I can imagine this will be the first issue faced by most users: https://answers.unity.com/questions/1373447/systeminfosupportscomputeshaders-always-false-on-a.html

I'm also getting a bunch of other errors here from the example scene (From the asset store btw):

Kernel 'AddVelocity' not found

UnityEngine.ComputeShader:FindKernel()

FluidDynamics.Main_Fluid_Simulation:Start() (at Assets/FluidDynamics/Scripts/Main_Fluid_Simulation.cs:147)

Kernel index (0) out of range

UnityEngine.ComputeShader:SetBuffer(Int32, String, ComputeBuffer)

FluidDynamics.Main_Fluid_Simulation:Update() (at Assets/FluidDynamics/Scripts/Main_Fluid_Simulation.cs:176)

Kernel index (0) out of range

UnityEngine.ComputeShader:Dispatch()

FluidDynamics.Main_Fluid_Simulation:Update() (at Assets/FluidDynamics/Scripts/Main_Fluid_Simulation.cs:177)

The last two goes on for a bit. Is there a setup process I'm missing?

 

One more thing. This one is maybe a nitpick, but your readme file mentioned to add a "Main_Fluid_Simulation" component. I usually search for my components after clicking Add Component on a GameObject. It confused me to see that it wasn't there. I looked at your code and realised that you named it differently in the dropdown menu. Would've been more intuitive to have the same name?

 

Thank you for your observation.
New online documentation

Seems like there is no unity support for Metal2 on Mac.
Also in online docs added instruction for Android target platform in Windows Unity Editor.

 

Pixel Art fire example

 

Looks great! Is it possible to implement colliders?

 

Yep, Fluid Dynamics already supports polygon colliders.

 

good and ncie

 

does this work on Unity WebGL?

 

It is possible to project those fluids on a 3D surface?
