Boids particles - setting Render as Object breaks simulation I have a boids system that moves its particles to a Goal avoiding certain objects.
This works fine when I'm testing with Render as Halo.
As soon as I change Render to an Object, or Collection, the simulation breaks and most of the particles slow down to a halt shortly after leaving the emitter.
Changing back to Render as Halo does not fix the issue.
Any idea what may be causing this?
initial state

final state with Render as Halo

final state with Render as Object
i think you changed the scale of your object, when you changed to render as object, right?
Just leave the scale as it is

and select your icosphere.
Press tab to enter edit mode, press A to select all then S to scale and scale this little guy up until you see enough and run simulation again.
