Hello,
When I'm compiling the GLSL shaders:
Vertex Shader:
struct ViewportClass {
float _from;
float _range;
float _max_range;
vec2 _fov_tan;
vec2 _clamp_min;
vec2 _clamp_max;
vec2 _size;
vec2 _center;
vec4 _FracToPosXY;
vec4 _ScreenToPosXY;
vec4 _PosToScreen;
};
attribute vec4 ATTR0;
attribute vec4 ATTR4;
uniform ViewportClass _Viewport;
void main()
{
vec4 _outVtx;
vec2 _outTex;
vec2 _outPosXY;
_outTex = ATTR4.xy;
_outPosXY = ATTR4.xy*_Viewport._ScreenToPosXY.xy + _Viewport._ScreenToPosXY.zw;
_outVtx = vec4(ATTR0.x, ATTR0.y, 1.00000000E+000, 1.00000000E+000);
gl_TexCoord[1].xy = _outPosXY;
gl_Position = _outVtx;
gl_TexCoord[0].xy = ATTR4.xy;
} // main end
Pixel Shader:
struct LIGHT_CONE {
float _length;
float _scale1;
float _angle;
float _angle_range;
float _vol3;
float _vol_max2;
vec3 _pos2;
vec3 _color6;
vec3 _mtrx[3]; // <- HERE IS _mtrx
};
vec4 _ret_0;
uniform LIGHT_CONE _Light_cone;
void main()
{
_ret_0 = vec4(_Light_cone._mtrx[0].x, _Light_cone._mtrx[1].x, _Light_cone._mtrx[2].x, 1.00000000E+000); // HERE I USE _mtrx
gl_FragColor = _ret_0;
return;
} // main end
I get following error:
Int params=0; glGetProgramiv(program,GL_ACTIVE_UNIFORMS,& params);
after calling the function params is still zero, while it shouldn't
it is not detecting "_Light_cone._mtrx" in the pixel shader.
it worked only if I moved the "_mtrx" to start of the struct
struct LIGHT_CONE {
vec3 _mtrx[3]; // <- to here
float _length;
float _scale1;
float _angle;
float _angle_range;
float _vol3;
float _vol_max2;
vec3 _pos2;
vec3 _color6;
};
There must be some kind of bug in detecting wheter this struct member is used.
