    I googled around, and looked all over this forum, and I can't seem to find any definitive answer, currently I'm developing a vr project which prefers atmosphere over raw detail, as such I would like to use extensively the vfx graph, but not having it in lwrp is a bit of a damper, is there currently any eta on lwrp support?

    Hi,
    VFX graph currently is fully compute shader based. We plan to add support for LW with compute shader short term (so it mean several platform will not work even if you use LW), long term VFX graph will be supported by LW with a CPU fallback but timeframe is not define (here we talk about a year).

    So, GLES3.1+ and Vulkan (on Android) will be supported?
    Any chance of getting this functionality in 19.1?

    To reiterate what Astarorr said, by several platforms, could you by any chance be specific? or is it still to far out at this time?

    Hi,

    I mean that we will support all the platform that Lightweight RP support that are able to run compute shader.
    We aim to add initial support with computer shader for LW for 2019.1. Visual Effect Graph still experimental so expect that some platform or thing may not work.

    Awesome, already have it up and running using 5.10.0. Great as now I can take advantage of VFX graph in oculus Go using OpenGL ES 3.1! Which ofcourse opens the door to so many possibilities :D

    I just created a LWRP project from Unity Hub, and added the VFX graph from the package manager. I still not able to see anything in the scene view. Is there any other setting you changed to make it work with 5.10.0? My Build settings are on windows now, but my plan is to work with Magic Leap.

    I am unsure as to why you wouldnt see anything in the scene view, hopefully someone else here can help?

    I always try a fresh reimport when I add in SRP packages, maybe try that?

    Now I got it working with a fresh LWRP project and using 5.10.0. Just one thing I did additional was to change this path(see image), before that I was not able to see anything. And also something weird is that I getting very unsaturated colors, but that I'm not sure if is related to the fact I'm on LWRP.

    This tutorial might be useful in this case.

    Anybody gotten VFX to run on iOS? LWRP + VFX working on Mac thanks to latest betas and you guys' tips, but Xcode is saying:

    Metal: Error creating pipeline state (Hidden/VFX/System 1/Quad Output): Compiler encountered an internal error

    Awesome. That's the part I've been missing.

    Annoyingly - I now remember doing this on a while back and then forgetting it

    Thanks loads for the reminder.

    Thanks for all the useful info and links folks!

    Would the Visual Effect Graph have a chance of working with LWRP in 2018.3, or you have to be on 2019.1? Also I'm curious if I'm not using neither HDRP nor LWRP but something custom, what would my custom system need to provide to be able to run Visual Effect Graph?

    Thanks!

    Hi I'm seeing a strange Behaviour:
    I have a scene with the basic VFX swarming particles.
    The scene is working perfectly on an iPad with iOS12.1. The exact same scene in tha App, built from the same Unity and XCode project does NOT showing ANY particles on an iPad Pro with 12.3 installed...

    XCode fires this debug message when the particles should be shown:

    2019-07-12 15:35:26.592595+0200 scenaVfx[787:167140] Compiler failed with XPC_ERROR_CONNECTION_INTERRUPTED
    2019-07-12 15:35:26.612826+0200 scenaVfx[787:167140] Compiler failed with XPC_ERROR_CONNECTION_INTERRUPTED
    2019-07-12 15:35:26.630017+0200 scenaVfx[787:167140] Compiler failed with XPC_ERROR_CONNECTION_INTERRUPTED
    2019-07-12 15:35:26.630041+0200 scenaVfx[787:167140] MTLCompiler: Compilation failed with XPC_ERROR_CONNECTION_INTERRUPTED on 3 try
    Metal: Error creating pipeline state (Hidden/VFX/System 1/Quad Output): Compiler encountered an internal error

    I'm using:
    Unity2019.1.1f1
    LWRP 5.13
    VFX 5.13

    EDIT: The same happens with
    Unity 2019.2.0B7
    LWRP 6.7.1
    VFX 6.7.1


    Thank you!

    Yes I'm getting the same error! How did you manage to make LWRP and VFXGraph work on iOS ?
    Thank you!

    I finally got it working....
    After days of testing and isolating the offending shader code, I found the core of the problem.
    The metal compilers on iPhoneX/iPad/iPhone6 are throwing errors on evaluation of curves.
    So replacing the sampling curves with gradient sampling. The errors went away.
