Hi there!

I've created a volumeplugin and applied it to an object, but when i'm trying to access it via

<CODE>var doc = GetActiveDocument();
var textag = op->GetFirstTag();

while(textag!NULL)
{
if(textag->GetType() == Ttexture)
{
var mat = textag#TEXTURETAG_MATERIAL;
println("FOUND IT: ", mat);
}
textag = textag->GetNext();
}</CODE>

the console always prints "nil" for my shader, but if i'm doing the same with a standard C4d material anything is going fine.

Did i missing something?

Ciao

Without knowing the sourcecode of your volumeshader it is a bit hard to say what is going on. In what language is the shader written, COFFEE or C++? The C++ SDK Volume shaders work fine for your little example. You can contact me under sdk_support(at)maxon.net if you want to keep your source code confidential.

cheers,
Matthias

Hi Matthias,

it is nothing special, just a simple dummy shader, mainly for getting access to some data of the shader to export it.
It is written in Coffee.

Found it, just included the .coh file in the wrong spot.
I worked to much on this plug, it was so obvious but i didn't saw it.

Anyway thanks Matthias.

A new problem arised.

Ok, i've got a menu plugin with the search routine in the first post and the shader plugin. Now I wanted to access the shader data with the resource descriptions like this

  
if(mat)  
{  
     var mattype = mat->GetType();  
     println("MATTYPE: ", mattype);  
     var matname = mat->GetName();  
     println("MATNAME: ", matname);  
     var matbc = mat->GetContainer();  
     println("MATCONTAINER: ", matbc);  
     var matdata = matbc->GetData(IDC_SUNFLOW_DIFFUSE_COLOR);  
     println("MATDATA: ", matdata);  
}

but to my surprise I couldn't access them, in fact I always received a nil for GetData. After searching the forum and the SDK, I found that there are two ways of accomplishing my task. 1.Pluginmessaging or 2.Storing the shader data to an object container.

So, what would be the best method and how and where is the best place to implement it?

Ciao
