How to make particles render even if is emittor out of camera in 2D ?

Hi everyone. If particle emitter move out of camera, long tail of particles disappear too. Visually it is very unpleasant. Do someone know how to make particles render even if is emitter out of camera ? thanks

I think you need to change the Visibility Rect so it covers everywhere the particles go. You can have Godot generate one for you by selecting the particles node, pushing the particles button above the viewport (on the same bar as the snapping tools), and then selecting "Generate Visibility Rect" from the drop down.

I have no idea if changing the Visibility Rect will work with particles emitting in world space though.

Because mentioned emitter is part of secondary fire projectile, generating one does not work right because it is on separated scene and instantiated later at runtime. Apparently, set Visibility Rect to 10 000 x 10 000 is big enough. Thank you

Ah, I didn't think about it being part of another scene. I'm not sure how to go about generating one in that case. I'm glad you got it working!

That is more than 10 times of size of play field. That is more than enough space. Sometimes, assigning variables manually is better.

That is true! Sometimes entering in the values manually is better. I'm just too used to using the built in stuff simply because "it's there" :lol:
