How to make a flat emitter?

hi all,

I used a random vec2 with polar to cartesian to generate positions within a circle. works in skia but idk why not in fuse. should be the same imo?

sprite renderer goes directly into my root scene
probability emit.vl (38.5 KB)

Just set a Y to 0 with SphereRandom

probability emit.vl (33.3 KB)

It works also this way but there are more particle in the middle.

your patch was black when I opened it. had to restart my pc.
this problem was not code related, thx.
