(Solved)Question about BlendOperation(SOLVED)

[CuteAlien]

You set the shadingLanguage to video::EGSL_CG, but then pass a hlsl shader.

Hmm Interesting never saw that, I changed it to

Code: Select all

video::EGSL_DEFAULT 

Sadly It changed nothing though.

--Edit: forget about this, I misunderstood everything--
HLSL doesn't work with OpenGL. Either change your driver type to EDT_DIRECT3D9, or use this GLSL equivalent to saturation.hlsl (I'm not sure if this will work):

Code: Select all

//saturation_vertexShader.vert
 
uniform mat4 matViewProjection;
 
varying vec2 texCoord;
 
void main(void) {
    gl_Position = matViewProjection*gl_Vertex;
    texCoord = gl_MultiTexCoord0.xy;
}

Code: Select all

//saturation_fragmentShader.frag
 
uniform sampler2D TextureSampler;
 
varying vec2 texCoord;
 
void main(void) {
    vec4 Color = texture2D(TextureSampler, texCoord);
    gl_FragColor = clamp((Color - 0.3) / (1.0 - 0.3),0.0,1.0);
}

Then you'll need to specify the paths of the new shaders:

Code: Select all

//don't use absolute paths
psFileName4 = "saturation_vertexShader.vert";
vsFileName4 = "saturation_fragmentShader.frag";
 
video::IGPUProgrammingServices* gpu = driver->getGPUProgrammingServices();
 
s32 saturation_pass = video::EMT_SOLID;
 
if (gpu)
{
    Saturation_Shader* mc_12 = new Saturation_Shader();
 
    const video::E_GPU_SHADING_LANGUAGE shadingLanguage =
        video::EGSL_CG; video::EGSL_DEFAULT;
 
    saturation_pass = gpu->addHighLevelShaderMaterialFromFiles(
        vsFileName4, "vs_main", video::EVST_VS_1_0,
        psFileName4, "ps_main", video::EPST_PS_1_0,
        mc_12, video::EMT_SOLID, 0, shadingLanguage);
    mc_12->drop();
}

Man I'm going to be honest I'm not sure why your telling me OpenGL doesn't work with DirectX? I know this.
Nowhere in my code which is just Irrlicht's simple RTT example do I say use OpenGL drivers but then pass an HLSL shader.

Those are just Irrlicht's default layout in the tutorials to check If the driver used is OpenGL or DirectX. I stated that this is a very simple app to test the problem.

If what your suggesting was actually the problem then none of my shaders would not work, not just one of them.

Sorry, my mistake.

After looking through this a bit better, I think you should be sending the sampler to the shader with the shader callback.

Just wanted to update that I fixed the problem I edited the shader, everything I was doing in the main.cpp was actually fine. I hard coded the values and did not use any float variables.

I also suspect for this particular shader saturate semantics may have been causing a problem also.

Thanks to CuteAlien and juanjpro.

[The_Glitch]

Don't mind the exposure haven't edited any values just testing the setup for now.

[CuteAlien]

Cool, looking nice :-)

[The_Glitch]

This one is a more fine controlled result.

[The_Glitch]

Even better lol Halo 3. Now only If Irrlicht supported cubemaps

[The_Glitch]

Crazy ass bloom LOL
