I've ran into this problem with 1.7.10 optifine where i cant see any capes or see mine. Yes capes are enabled in settings but they just are not popping up here is a link to my Name MC profile https://namemc.com/profile/Prrrrfftt.1 where it says i have my cape. I can confirm i do own a cape because i've asked multiple friends and they all say they can see mine. https://namemc.com/profile/Prrrrfftt.1 Thanks for Reading this Post. -Sev
