Hero Glow

How do I remove the heroglow or how do change the color so all heroes in a team controlled by diffirent players have the same glow.

ffs there are a LOT of topics about this, just do a simple search or read tutorials

Well, most of the tutorials i've read on Hero Glow do not work anymore in TFT

It's true. They don't work in TFT. To remove the teamglow from heros, you have to manually edit the hero's model and import the edited model into your map.
Not a good idea, as far as map size is concerned.
To change the color, I believe there is a "Unit - Change color" action.
