I searched the forums, and it seemed like the only way to remove hero glows was to do a reinstall/mdl/mdx editing... is there a simple way to remove the glow from a single unit on a custom map without all that hassle?
In RoC there was; you could overwrite the skin that the glows all use, and they wouldn't appear. However, since the release of TFT, no. You gotta do model edits.
