PSX Shader NB

This shader pack is a fork of ckosmic's Minecraft PSX Shader, which recreates the visual style and atmosphere of games for the original PlayStation 1.

Main Changes in the Fork

In this version, the vertex transformation system has been modified, completely removing the "bouncing" effect of objects when moving the camera. This effect was a characteristic feature of the original shader but could cause discomfort for some players.

Technical Features

To achieve stable image quality, the following shader files have been reworked:

• shaders/gbuffers_entities.vsh
• shaders/gbuffers_hand.vsh
• shaders/gbuffers_basic.vsh
• shaders/gbuffers_armor_glint.vsh

The key change concerns vertex transformation - the code was modified from the original version:

vec4 position4 = mat4(gl_ModelViewMatrix)  vec4(gl_Vertex) + gl_ModelViewMatrix[3].xyzw;

vec4 position4 = gl_ModelViewMatrix  vec4(gl_Vertex);

Installation and Compatibility

For installation, simply place the shader pack archive in the shaderpacks folder in the Minecraft directory. The pack is compatible with both OptiFine and Iris - two popular modifications for working with shaders.
