Hi, I'm using Origins 0.7.3.9 for 1.16.5 and Forge 36.2.19 and I've noticed two issues with the phantom origin. Firstly, going through blocks does not cause blindness like on the fabric version.
And next, while I am transparent in first person, I am not transparent in F5 view nor am I transparent to other players. I remember being transparent in earlier versions, so this may be an issue with Optifine. Thanks for your time.

@apertureos its issue with optifine. i try it without optifine and everythink is good.
origins mod doesn't like optifine.
