I made a flashlight that i want to parent to the player view of atlas and i dont know how to do it. I tried parenting it to the eyes attachment of the playermodel but the eyes arent following the player view very precisly so its not very good. Anyone know how to parent something directly to the player view/camera?

I found this page on the VDC, but I don't know if this will help you, since you're doing co-op.

(Likely no longer relevant given the long hiatus, but for future reference)

Use a logic_measure_movement set to "eye position". It works better than parenting for following a camera.
