are you changing the colors in a script when you play the game?
if so that’s why they’re changing and if you’re asking why it isn’t changing after in studio as well that’s because you’re changing it in the game script not in studio
I am not changing any of the colors through a script. I opened a blank baseplate and imported the models that are having the highlight issue. You can reproduce it through the reproduction file.
Pretty sure the only workaround for this currently is to modify any property inside the highlight (I.e. toggling enabled to false and then setting it to true again)
