Spawn many particles on a procedural mesh

panicq

Hey,

I would like to know what would be the approach to spawn particles on a procedurally generated mesh in godot ?

I've seen that the GPU particles have the ability to do this from the editor: https://godotengine.org/article/godot-30-progress-report-6

but I don't find how to test this by script and if the performances would be good enough to be called at runtime when the mesh updates .

Moreover I need static particles that never die, is this possible with the particle node ?

Thank in advance for your help.

Unfortunately, the particle emission point generator is only exposed in the editor, not in running projects.

You can set the particle lifetime to a very large value like 1000000000 to alleviate this. It will be able to run for several decades continuously :)

Hum ok, that's sad. Thanks anyway
