Post-processing material parameter

[michal]

hi,

I would like to know if it is possible to set a parameter for post-process material via C++ API.

 

                  Unigine::Render::setPostMaterials("post_hblur_gauss");

      // like  Uniigine::Render::setPostMaterialParam("Radius",2.2);

thanks

Hey Michal,

this thread should help you out:

You can find the .basemat-file in your sdk installation: data/core/materials/default/post/post_hblur_gauss.basemat
You need to inherit it and change the parameter just like in the linked thread.

Best regards

Dear @michal,

Set post process material in Editor. Or you may set it using C++ api.

 

In AppWorldLogic::update. Just a simple step like this.

    const char* stringMaterial = Render::getPostMaterials();
    MaterialPtr material = Materials::findMaterial(stringMaterial);

    rTimeThatGoesForever += Game::getIFps();
    float fValue = sin(rTimeThatGoesForever);

    material->setParameterFloat("radius", fValue);

This is just an example. Actually, the string returned will be combined one separated with comma. So you need to separate the material names and use them.

yes this exactly occurred to me first, when I didn't see the change so I thought
I'm going for it wrong. Now I tried to use "post_filter_sobel" instead of "post_hblur_gauss" and the scale parameter and the material is really changing.

thanks
