Hello,

I am trying to access custom channels and am stuck after getting to the user data of the material.
How do I get to the BaseChannel object which I presume is of type DA_ALIASLINK?

  
BaseTag* bt = obj->GetTag( Ttexture, 0 );  
  
BaseMaterial* mat = (TextureTag * )bt->GetMaterial( true );  
  
//trying to access custom channels  
DynamicDescription *dd = mat->GetDynamicDescription();  
if(dd)  
{  
  DescID dscID;  
  const BaseContainer *bc;  
  void *dscHnd = dd->BrowseInit();  
  while(dd->BrowseGetNext(dscHnd, &dscID, &bc))  
  {  
      if( dscID[1].dtype == DA_ALIASLINK ) //DA_ALIASLINK -> BaseLink  
      {  
          // how to access the channel object ?  
          BaseChannel* chan = ?  
      }  
  }  
  dd->BrowseFree(dscHnd);  
}
