The main feature of Fluid Flow is the dynamic fluid simulation.
This is a paid asset, but now you can download for FREE, but please remember this package is provided only for learning purposes or to be able to test before buying the product, NOT FOR COMMERCIAL PURPOSES.
Detail this asset from Unity Store: Original Link
Fluid Flow 2 v2.3
Download Now We encourage you to download all the assets from the developers. These assets we share are for personal use and to gain some good knowledge with high quality assets.
However, you can also use it just for real-time 3D texture painting/decals, which also supports skinned mesh renderers.
Due to its modular structure, you can decide which parts of Fluid Flow you want to use, without unnecessarily bloating your project.
Try the WebGL demo!
Check out the documentation.
The texture painting and flow simulation are handled fully on the GPU for optimal performance.
Fluid Flow is not a 100% physically accurate fluid simulation, but it provides good-looking fluid for your games at a very low performance cost!
As fluid is painted and simulated in UV space, your meshes require a UV unwrap with non-overlapping UV islands, so there is a 1:1 correlation between the object's surface and the texture.
You can also configure Fluid Flow to use the lightmap UV set, which can be generated by unity automatically.
Please note that your objects require a special shader for overlaying the fluid, or when using the texture atlas system.
There are basic surface and shader graph shaders included. Alternatively, you can easily create your own supported shaders with the provided custom shader graph nodes, or shader utility functions.
Tested successfully on windows, android, and WebGL.
