PSX Shader NB
This shader pack is a fork of ckosmic's Minecraft PSX Shader 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:
vec4 position4 = mat4(gl_ModelViewMatrix) * vec4(gl_Vertex) + gl_ModelViewMatrix[3].xyzw;
to standard transformation:
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 quadratic distance falloff, 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 and Iris.
