Hello,
I am trying to read the LINK from TextureTag, but I always get a
NULL - Pointer . The other datas from TextureTag could I read.
Here is some part of my code:

void explore_tag(BaseObject *base)
{
BaseContainer bc;
BaseMaterial *bmat = NULL;
BaseList2D *bl = NULL;
BaseTag *tag = base->GetFirstTag();
BaseDocument *doc = GetActiveDocument();

for (; tag!=NULL; tag = tag->GetNext())
{
  GePrint("    TAGS: "+tag->GetName());
  bc = tag->GetData();

  // bl = bc.GetLink(TEXTURETAG_MATERIAL,doc);
  //bmat = bc.GetMaterialLink(TEXTURETAG_MATERIAL,doc);

  bmat = bc.GetMaterialLink(TEXTURETAG_MATERIAL,doc);

if (bmat) GePrint("BaseMaterial vorhanden");
  Real x = bc.GetReal(TEXTURETAG_LENGTHX);
  Real y = bc.GetReal(TEXTURETAG_LENGTHY);
  GePrint("X: "+RTS(x)+" Y: "+RTS(y));
  LONG mapping = bc.GetLong(TEXTURETAG_PROJECTION);
  String res = bc.GetString(TEXTURETAG_RESTRICTION);
  GePrint("Restriction: "+res);
  switch (mapping)
  {
  case (0) : GePrint("Kugel-Mapping");break;
  case (1) : GePrint("Zylinder-Mapping");break;
  case (2) : GePrint("Fläche-Mapping");break;
  case (3) : GePrint("Quader-Mapping");break;
  case (4) : GePrint("Frontal-Mapping");break;
  case (5) : GePrint("Spat-Mapping");break;
  case (6) : GePrint("UVW-Mapping");break;
  case (7) : GePrint("Shrink-Mapping");break;
  }
}
}

Where is the problem or error ??

*bump*

same problem here. didnt want to start a new topic.

BaseTag *baset = obj->GetTag(Ttexture,0);
BaseContainer basec = baset->GetData();

BaseMaterial *bm = basec.GetMaterialLink(TEXTURETAG_MATERIAL, doc);

always returns a null-pointer. could use some help

Try this instead:

GeData data;  
ttag->GetParameter(DescID(TEXTURETAG_MATERIAL), data, NULL);  
Material* mat = static_cast<Material*>(data.GetLink(doc, Mbase));  
if (!mat) return FALSE;
