Alternative Shader [AS]
AS is a powerful, but lightweight resourcepack, that almost fully rewrites minecraft's graphic code (GLSL) to get incredible look with minimum performance impact, with a support of every block/entity from any mod that you can think of
AS Works completely on client and doesn't require any mod, only using Core Shaders
Installation Guide
This is resourcepack, that doesn't require any mods, so you just need to drag it into texturepack folder on 1.21.1 and turn on fabulous
Warning: Officially AS distributed ONLY on modrinth, i do not recommend downloading it from any other source

This Resourcepack (Vanilla Shader) includes
- Generating PseudoPBR in Real Time
- Light Pathfinding (kind of, obviously only imitation)
- Realistic shadows
- Brighter graphics
And much more!
Known Issues
- Incompatibility with sodium and other mods, that changes minecraft rendering, or doesn't support Core Shaders
Recommendations
- Highly recommended to use Fabulous, Fast or Fancy would break some parts (Only to 2.0+ Versions)
- Recommended to use AS with more than 8 render distance
