[Closed] 3dsmax SDK – Get diffusemap from architectural material

I’m stuck at fetching a reference to the texture in the diffuse slot in a architectural material.

My usual bag of tricks does not seem to work, can anyone of you point me in the right direction?

I have tried to scan the paramblock and get it by name:

 for (int i = 0, count = mat->NumParamBlocks(); i < count; ++i)
 {
 	IParamBlock2 *pBlock = mat->GetParamBlockByID(0);
 	for (int j = 0, count = pBlock->NumParams(); j < count; ++j)
 	{
 		if (pBlock->GetLocalName(j) != NULL)
 		{
 			mprintf(_T("
 checking param %s 
", lmutil->getstring(pBlock->GetLocalName(j))));
 			if (::_stricmp(pBlock->GetLocalName(j).ToCStr(), "diffuseMap") == 0)
 			{
 				BitmapTex *tmap = (BitmapTex *)pBlock->GetTexmap(j, GetCOREInterface()->GetTime());
 				OutputDebugStringW(_T("
Found diffusemap: %s
", tmap->GetFullName()));
 			}
 		}
 	}
 }

but it never seems to find the param by name.

Also I tried to just ‘brute force’ it by fetching it form the param index (
(type: showproperties $.material in listener with a object with arch material applied, you will see it
litst the diffuseMap as param 26 in 0-based index).

for (int i = 0, count = mat->NumParamBlocks(); i < count; ++i)
 {
 	IParamBlock2 *pBlock = mat->GetParamBlock(i);
 	//26 is diffuse map.
 	BitmapTex *tmap = (BitmapTex *)pBlock->GetTexmap(26, GetCOREInterface()->GetTime(),FOREVER,0);
 	if (tmap != NULL)
 	{
 		mprintf(_T("
 Architectural Texturemap is defined %s 
", tmap->GetName()));
 	}
 }

Also this does not seem to fetch it…

BitmapTex *tmap = (BitmapTex *)mat->GetSubTexmap(ID_DI);
			if (tmap)
			{
				mprintf(_T("
 Architectural Texturemap is defined %s 
", tmap->GetFullName()));
			}

All I want is a reference to the bitmap in the diffuse slot, so that I then can get the texture map name\path, but as you see I’m stuck at getting it…
