I also notice that there is no doc->EndUndo() in UpdatePlanet() and no AddUndo()s either. Maybe you should comment out the doc->StartUndo() until it is needed.

Thanks Robert,,, I have decided that in the UpdatePlanet function I am going to use GetDown, GetNext, and GetFirstMaterial to reference the materials and objects in the scene.

I am running in to one problem though...

The GetFirstMaterial() function is derived from the BaseMaterial, but my materials are from the Material Class.. Is it possible to use GetFirstMaterial on materials from the Material class?

You should be able to up-cast the BaseMaterial* returned by GetFirstMaterial() to Material* without any issues. Just use a C cast (Material* ) or a C++ one static_cast_<_material*_>_

Could you give me a code snippet of how that would look?

great thanks Robert...

Now I need to change the fresnel settings of the color channel on a material. so I am trying to use

atmosphereMat->SetParameter(MATERIAL_COLOR_SHADER,?,NULL);

But i am not sure what to put in the ? part.... or do I need to use a different constant other than MATERIAL_COLOR_SHADER?

I would expect that you should be able to get away with:

atmosphereMat->SetParameter(MATERIAL_COLOR_SHADER,GeData(shader),NULL);

where shader is a pointer to the shader being added to the SHADERLINK.

so would that shader be (Xfresnel) ?

This is what I tried.. and I still get nothing in the TEXTURE field of the Color Channel.

atmosphereMat->SetParameter(MATERIAL_COLOR_SHADER,GeData(Xfresnel),NULL);

Any other thoughts?

Thanks a lot for your help.

No, I think it will need to be an actual allocated shader:

PluginShader* shader = PluginShader::Alloc(Xfresnel);

Also, there is another way from c4d_basechannel using HandleShaderPopup(). No experience with it though.

You might want to try going through the BaseContainer then:

atmosphereMat->GetDataInstance()->SetLink(MATERIAL_COLOR_SHADER, fresnel);

GeData() can't handle general pointers (only BaseLink* ).

I think you may be stuck with HandleShaderPopup() then. I couldn't find anything here, in the docs, or in the cinema4dsdk that describes how to set a channel shader.

It is also possible that you need to insert the shader into the material:

atmosphereMat->InsertShader(fresnel, NULL);

Then try to set the link. Again, I don't see any examples or more explicit information on this.

LOL.. okay so after a few hours of searching a trying, I am at somewhat of a loss again.. How would I change the color of the knots that are in the fresnel shader?

Here's what I have so far.. This inserts the fresnel shader in to the material for both the color channel and the transparency channel. And with the current code it completely removes the color knots from the gradient in both fresnel shaders. So I feel like I'm on the right track.. any help would be greatly appreciated.

  
          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);

Does anyone know how I would add color knots to the gradient in the fresnel shader that I have added with the above code?
