Why use Bliss Shaders?
Bliss Shaders stands out among other shader packs for its fine control over atmosphere and lighting, especially fog behavior per biome something rarely seen even in high-end shaders. It blends cinematic quality with practical features like hiding chunk loading gaps using soft fog and providing consistent framerate on mid- to high-end systems.
If you’ve used Chocapic13 or BSL and want more freedom, Bliss is a fantastic upgrade, especially for content creators or players using realistic texture packs.
