# PSX Shader NB<\/p>\n
This shader pack is a fork of ckosmic’s Minecraft PSX Shader that mimics the look and feel of PlayStation 1 graphics.<\/p>\n
## Changes in this Fork<\/p>\n
### No-Bounce Vertex Fix<\/p>\n
Changed vertex transformation to eliminate the bouncing effect when moving.<\/p>\n
Changed the vertex transformation from:<\/p>\n
“`glsl
\nvec4 position4 = mat4(gl_ModelViewMatrix) * vec4(gl_Vertex) + gl_ModelViewMatrix[3].xyzw;
\n“`<\/p>\n
to standard transformation:<\/p>\n
“`glsl
\nvec4 position4 = gl_ModelViewMatrix * vec4(gl_Vertex);
\n“`<\/p>\n
### Dynamic Hand Light<\/p>\n
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.<\/p>\n
## Installation<\/p>\n
Place this shader pack in your Minecraft `shaderpacks` folder.<\/p>\n
This shader pack works with both OptiFine and Iris.<\/p>\n
