I’ve managed to get glows working by adding a delay of 2 seconds for granting to a player when they initially spawn, as its to colour code teams at all times.
However the glow HAS to be set to seen by local player, and it has to be a glow, outline does not work 100% of the time.
If you use other settings the chance of it succesfully applying to the player decreases as well as the chance it gives the player the wrong colour.
This is a very useful device and would be nice if the settings worked as intended at all times.
