So I have created materials and objects in the plugin that I am working on.   I would like to add the fresnel shader to the COLOR channel and change the colors within that fresnel shader.   Can someone explain to me how this is done?

I have been using :

SetParameter() to set the Color Channel's parameters but the parameter for the color channel that houses the fresnel shader is...

SetParameter(MATERIAL_COLOR_SHADER,?,NULL);

I am not sure what to put for the ? argument..   or if this is even the correct course of action.

Please any help would be greatly appreciated.

Thanks,

~Shawn

I solved this problem with :

  
  
          atmosphereMat->InsertShader(fresnelColor, NULL);   
  
          atmosphereMat->InsertShader(fresnelTrans, NULL);   
  
          atmosphereMat->GetDataInstance()->SetLink(MATERIAL_COLOR_SHADER, fresnelColor);   
  
          atmosphereMat->GetDataInstance()->SetLink(MATERIAL_TRANSPARENCY_SHADER, fresnelTrans);   
  
          fresnelColor->SetParameter(SLA_FRESNEL_GRADIENT,ATMOSPHERIC_COLOR, 0);   
  
          fresnelTrans->SetParameter(SLA_FRESNEL_GRADIENT,Vector (0,0,0), 1);   
  

Now I need to insert color knots into the gradient of the fresnel shader and change their color?

Any idea how to do this?

Thanks,

~Shawn

The Fresnel shader's colors are actually knots of a gradient. They are part of the GradientCustomGui custom GUI and can be accessed through the Gradient custom data type. Please have a look at the GradientShader.cpp SDK example.
