The options to check are as follows:

enable-self-host

This will be updated in the future, but please make sure to set it to false

look-degree

Displays when within the field of view.

look-distance

Defines the maximum distance at which the healthbar is visible.

build-folder + pack-type

pack-type: folder #folder, zip, none
build-folder: "BetterHealthBar/build"

If you are using Nexo, set pack-type to none. This allows the pack to be automatically merged when reloading Nexo. If you do not want automatic merging, change pack-type to zip and set build-folder as follows:

build-folder: Nexo/pack/external_packs/betterhealthbar3  

If you are not using Nexo, the resource pack will be generated in the build-folder location. merge it manually.

shaders

shaders:
  text.vsh: true
  text.fsh: true
use-core-shaders: true

To make the shader visible to players while active, set use-core-shaders to false

For better performance, it is recommended to keep it true.
