This pack provides you with full bright night vision, you can now navigate caves and dark environments with ease and clarity. It requires enabling Render Dragon experimental features and works only in Deferred Technical Preview graphics mode.

Full Bright Night Vision provides permanent night vision using the deferred technical preview graphics mode.
It doesn’t require a behavior pack and is currently only compatible with preview versions of the game.
Once the new render dragon features are fully rolled out, this pack should be available for use in normal versions of the game.
Enjoy!
