Created attachment 38707 [details] test case GLSL spec 1.1 section 7.5 mentions below variables are built into GLSL: gl_TextureMatrixInverse[gl_MaxTextureCoords] gl_TextureMatrixTranspose[gl_MaxTextureCoords] gl_TextureMatrixInverseTranspose[gl_MaxTextureCoords] But they are not supported in either glsl2 or the old glsl compiler. The attached case gets below compiling error: Failed to compile fragment shader TextureMatrixInverse.frag: 0:5(34): error: `gl_TextureMatrixInverse' undeclared 0:6(36): error: `gl_TextureMatrixTranspose' undeclared 0:7(43): error: `gl_TextureMatrixInverseTranspose' undeclared Shader source: void main() { mat4 result; result = gl_TextureMatrix[0]; result = gl_TextureMatrixInverse[0]; result = gl_TextureMatrixTranspose[0]; result = gl_TextureMatrixInverseTranspose[0]; }
