    Hi thomas4d,
    I have the same problem. In the unity editor and Windows build everything works fine but in the WebGL build nothing appears.
    Then, I could now isolate the problem using the default template project and add the simple swarm particle systems.
    In the firefox browser console, there is a hint, that the shaders cause the error (see below). However, I could not find how to change the shader in VFX Graph.
    I submitted a bug report to Unity (http://fogbugz.unity3d.com/default.asp?1218132_v8a55fatsfrbss0s). Let's see if they send an answer.

    any progress on this? Afaik compute shaders dont work for webGL yet in unity.. and vfx graph heavily relies on compute shaders

    I've been looking for that as well, there seems to be progress but I couldn't find anything recent that would make me hope this will be available soon. That would be so freaking awesome to use the VFX graph in WebGL....

    WebGPU will support it - but I wouldn't hold your breath for WebGL. Looking forward to selecting WebGPU from build options, though given the tech is still a "working draft" I don't expect to see that for some time (as in years), since I don't think many resources will be invested in it until the spec is finalized. Even then, it won't be available in the editor overnight. I'd love to be mistaken :D

    It's not in the hands of Unity.
    The WebGL API isn't and won't support it.
    At one of the latest WebGL/WebGPU community meetups, the WebGL and WebGPU working group members told that it would be a feature of WebGPU and won't be supported in WebGL

    Thank you for this. I kind of thought it would take a few years, but telling me it's coming in WebGPU gives me more to look out for. In the mean time I will make less performant versions of my render code with scripting symbols, my particles and grass will take a hit haha.
