PSX Shader NB

# PSX Shader NB This shader pack is a fork of ckosmic's [Minecraft PSX Shader](https://github.com/ckosmic/minecraft-psx) that mimics the look and feel of PlayStation 1 graphics. ## Changes in this Fork ### No-Bounce Vertex Fix Changed vertex transformation to eliminate the bouncing effect when moving. Changed the vertex transformation from: ```glsl vec4 position4 = mat4(gl_ModelViewMatrix) * vec4(gl_Vertex) + gl_ModelViewMatrix[3].xyzw; ``` to standard transformation: ```glsl vec4 position4 = gl_ModelViewMatrix * vec4(gl_Vertex); ``` ### Dynamic Hand Light Added real dynamic lighting from held light sources (torches, lanterns, etc.). Light now updates continuously as you move, rather than only when breaking/placing blocks. Uses `heldBlockLightValue` / `heldBlockLightValue2` uniforms with linear distance falloff matching vanilla placed light behavior, applied to terrain, entities, water, hand, and basic geometry shaders. Supports both main hand and off hand light sources. ## Installation Place this shader pack in your Minecraft `shaderpacks` folder. This shader pack works with both [OptiFine](https://optifine.net/) and [Iris](https://irisshaders.net/). ## Credits - Original shader by ckosmic - Iris compatibility by Karen/あけみ (akemin_dayo) ## License Licensed under the [MIT License](https://choosealicense.com/licenses/mit/).
