such the glenable(gl_texture_2d) doesn’t effect the glsl frag
and i don’t want to send some the control message whether the texture is enable or not into the shader
I usually use this method:
if (textureSize(map, 0).x) {/have texture bind/}
else {/no texture bind/}
to know when i need the texture mapping in glsl
and the default texture color is all black which is not good for the dynamics model’s texture mapping
can you add a function like:
if (textureAvaible(map)) {/have texture bind/}
else {/no texture bind/}
thank for the good GLSL.
