This is a simple texture pack for Minecraft 1.12.X - 1.20.X that makes the HUD and most GUI elements transparent. I did make a version for 1.8 (and lower) for anyone who refuses to adopt the new combat system or just enjoys the old feeling of the game (link can be found below). If you have any suggestions let me know in the comments!
