Why doesn't this vertex+fragment shader work?
Unity throws the following error with this shader: "Shader warning in 'GLSL basic shader': Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)".
It's a very basic shader, I don't see why it doesn't work.
Shader "GLSL basic shader" { // defines the name of the shader
SubShader { // Unity chooses the subshader that fits the GPU best
Pass { // some shaders require multiple passes
GLSLPROGRAM // here begins the part in Unity's GLSL
#ifdef VERTEX // here begins the vertex shader
void main() // all vertex shaders define a main() function
{
gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex ;
gl_Position = gl_Position * .1;
gl_Position = vec4(0.0, 0.0, 0.0, 0.0);
// this line transforms the predefined attribute
// gl_Vertex of type vec4 with the predefined
// uniform gl_ModelViewProjectionMatrix of type mat4
// and stores the result in the predefined output
// variable gl_Position of type vec4.
}
#endif // here ends the definition of the vertex shader
#ifdef FRAGMENT // here begins the fragment shader
void main() // all fragment shaders define a main() function
{
gl_FragColor = vec4(0.0, 1.0, 0.0, 1.0);
// this fragment shader just sets the output color
// to opaque red (red = 1.0, green = 0.0, blue = 0.0,
// alpha = 1.0)
}
#endif // here ends the definition of the fragment shader
ENDGLSL // here ends the part in GLSL
}
}
}
