Geometry Nodes: Can't get emitted objects to stay with the emitter

I’m following the Fireflies tutorial by Default Cube. Everything works fine except for one thing: supposedly, I should be able to move my Suzanne around and have the ‘fireflies’ follow it, but when I do they all stay around the origin. Also creating new objects in the ‘fireflies’ collection creates new fireflies, but again around the origin. Any idea what I did wrong?

Hi Bart,

You need to check this,


hope that helps!

Ah thanks but that wasn’t it. I found the solution deep down in the comments on the video - you have to plug the vector math node into offset instead of position. I suppose this changed since the video was made.
