textureMatrix

Danger

This uniform only works with the “core profile” in Minecraft 1.17 and newer. It is recommended to use the “compatibility profile” with Iris for better support.

uniform mat4 textureMatrix;

Transforms texture coordinates. Used by gbuffers_armor_glint to scroll the texture over time.

vec2 coord = (textureMatrix * vec4(vaUV0, 0.0, 1.0)).xy;

Equivalent to gl_TextureMatrix[0] in the compatibility profile and older GLSL versions.

vec2 coord = (gl_TextureMatrix[0] * gl_MultiTexCoord0).xy;
