    Hello! Mike here.

    The question is in the header basically. Is it in development or is it planned on a long road? Could you provide approximation for when it will be ready? Very important for my project.

    Also, is it possible to add custom external screen space fluid renderer to the system? To do it I need to find a way to transfer particle data on update to the external shader (From GPU to GPU). Is there a way to do so? If not, would it be hard to download the source code of VFX graph and patch it myself? Is it even possible?

    Hi Mike,

    Fluid simulation is under consideration at the moment, but it is not being worked on at the moment.
    You can check out our public roadmap here and vote for features you are interested in.

    The VFX graph is a package, so all the C# code for it is available already. You can copy your Visual Effect Package folder into the Packages folder of your project if you would like to modify the code.

    Hope this helps!

    Screen space fluid rendering should be possible to implement using an HDRP custom pass.
