Hey
I'm trying to get my plugin to key frame the changes in a texture tag. I'm just wondering how do I access the "Material" property of a data key on a material track?
Thanks

Thanks a lot for the quick reply. I guess I was hoping for the code to set the material property for the data key. I tried using:
```
    
    
      
    //material is a BaseMaterial which is parameter passed in  
    GeData d = GeData(material->GetData());  
    key->SetParameter(DescID(DATAKEY_VALUE), d, DESCFLAGS_DONTCHECKMINMAX);  
    
```
It doesn't appear this works. Any ideas on what's wrong? Or is there a better way of doing this?

GetData() returns the data container, not a GeData. You need to create a BaseLink and send in a GeData with that to SetParameter() :
```
    
    
    AutoAlloc<BaseLink> link;  
    link.SetLink(material);  
    key->SetParameter(DescID(DATAKEY_VALUE), GeData(link), 0);
```

Thanks a lot Mikael! Works perfectly after a few small modifications. Here's what I had to change if anyone's interested:
```
    
    
      
    AutoAlloc <BaseLink> link;  
    link->SetLink(material);  
    key->SetParameter(DescID(DATAKEY_VALUE), GeData(link), DESCFLAGS_DONTCHECKMINMAX);  
    
```
Thanks again
