Particle2D showing full texture and not region specified

Godot version

System information

PopOS

Issue description

I have a sprite map/atlas and for a Particle2D texture I have set a region as shown below.

However, when the particle is emitted, it shows the full texture

I did search for an existing one, apologies if already a bug.

Steps to reproduce

Exactly as above really

Minimal reproduction project

No response

I've just checked the documentation and it says this:
Note: Unlike CPUParticles2D, Particles2D currently ignore the texture region defined in AtlasTextures.

So is this why? If so, two questions:

1. Why is the setting still in the properties and why no hint given when it's known it is a particle2D and not a cpu particle, making everyone think texture regions are supported?
2. Is this a limitation of OGL or just a bug/feature not implemented in Godot?

AtlasTexture is just a wrapper for the texture on GPU. Most nodes draw textures using the regular texture draw function, which handles AtlasTexture in a specific way, but GPU particles work differently. You e.g. need a special material to use animations, so not sure if handling atlases in particles is possible. It would need to be done explicitly in the shader.

@KoBeWi
Ok (sorry, I replied by email, maybe it didn't arrive). If this doesn't work as expected how come the IDE lets you happily do it and the hints provide no indication either. Should this facility be disabled or at a least a tooltip hint provided (there is none) that at least tells people atlas textures don't work for particle2D?

Makes sense.

Ok, thanks. So why does Godot allow us normal folk to believe it's all fine to use them and no help shown in the gui. Could this be added?
