    Hello, This looks like a bug, sorry about that. Would you be able to send the effect so I can investigate?
    Are there any errors in the console?

    Bump*
    Still getting this issue in 2021.3.10f1. We downgraded our project to 2020's latest LTS and VFX Graph works since when we tried 2031.3.4f1 it didn't work with VFX graph at all and the same issue persists.
    1. Create a new project in 2021.3.10f1 using the urp sample project.
    2. Create a VFX graph and drag and drop it into the scene.
    3. Check alive/efficiency curve and on my end there is no particles and no system generated for the particles inside the Alive tab.
    No errors show up on Console either.
    Switching to 2020 LTS fixes the issue and VFX Particles work.

    Someone on YouTube mentioned that it could be exposure weight but I have no clue since that option doesn't work in URP. None of the Output nodes get a particle spawn either. Even the default VFX graph doesn't work. Even in builds they do not show up. And the alive/efficiency charts don't show any particles being spawned.

    Hey! Can you try adding a SetPosition(0,0,0) block in your Init and see if it fixes it?

    Same issue. Particles don't show up in the Control panel and no particle systems are "generated".

    @Blue_Lemon, @Kabookie Hi, we are not able to reproduce the issue on our side. Could you report a bug with the project where you were able to reproduce (please don't delete the Library folder), so we could investigate further (and share incident number (IN - XXXX) here)? Also, when creating visual effects or updating the project from 20.3 - 21.3 do you have Shader dependencies generated? upload_2022-9-22_11-53-32.png

    creating visual effects in a blank project with the default VFX asset, no shader dependencies get generated in 2021.3.10f1
    just submitted a bug report with the whole project attached, should be incident IN-17707.
