gl_MultiTexCoord0

gl_MultiTexCoord0

Valid Programs: gbuffers_*.vsh, shadow.vsh, any composite-style pass.

---

The vertex texture coordinate attribute.

Usually the coordinate in gl_MultiTexCoord0 corresponds directly to the atlas texture coordinate, however some geometry (such as enchantment glint) requires a texture matrix. Therefore, it is always recommended to use gl_TextureMatrix[0].

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

in vec2 vaUV0;

Danger

This attribute 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. See this page for more information.

It is always recommended to use textureMatrix.

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