Question

Hi, I’m trying to initialize and position an array of GPUParticles2D using the Rendering Server in Godot, but I’m having trouble with it.
I am unable to render these in Godot, yet no errors are thrown in the console.
Can anyone help me figure out what I’m doing wrong or link me to an answer for reference?
I’ve looked around but couldn’t find any good examples with particle systems. Can anyone point me in the right direction?
