    Hello everyone, I was trying to add a basic trail to my particles

    However after setting up a gpu event, the particles that should spawn from it are invisible (as you can see on the image below) upload_2021-12-4_14-59-30.png

    If I change the "sort" property on the Output Particle Quad node to "Off", particles do show up. But they will spawn in the local coordinates 0,0,0 and no matter what I do they wont move from there (in this image I set velocity to 0,1,0 and yet they wont move)

    Many times before I could use GPU Events just fine, without the need to change the sort property. If anyone knows how to fix this weird behavior, it is very much appreciated

    I guess it's because you are missing Update Particle block between init and output.
