[Forge] Entity X-Ray
I used the vanilla glowing method to achieve this goal.
If you add the mob to a team, the entity's color will be changed to the team color!
1.17 has some mobs that only get added when you breed/spawn them
Optifine has problems with it
I hope you enjoy it :)
However: It is still a hack, you can get banned!
PS: Also works against invisibility
