GPUparticles3D that follow a path3D

[mddm1]

Describe the project you are working on

Simple fish game.

Describe the problem or limitation you are having in your project

I need to bake the point texture and is cumbersome.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Add spawn position so that is not points or directed points but rather a path3D.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

simply add a path 3D node to spawn position just like in @export var.

If this enhancement will not be used often, can it be worked around with a few lines of script?

there are workarounds but are cumbersome.

Is there a reason why this should be core and not an add-on in the asset library?

it is an easy to implement quality of life on particles?

Moving to discussion, as there is no concrete technical implementation provided.

Also, this is already feasible. You can move your GPUParticles3D node along the Path3D node by making it a child of a PathFollow3D node, and animating its offset using an AnimationPlayer, Tween or code.

What's not supported yet is emitting particles along a skinned mesh, which is much more complex to implement.

I was looking at this part of documentation. I want the fish to move in a path3D way. NOT the whole particles node. Make the fish all follow the path as particles. How should I explain this?
