What is wrong with this code? I've tried without COPY_NO_INTERNALS, but the links to the Texture tags are then broken. I've tried calling AliasTrans::Translate after each and at the end (as shown). Is the AliasTrans::Init() document correct (source)? This is getting frustrating as it works to an extent, but the materials don't update properly (show the texture image) and rendering fails.

Okay, this code is mostly working, but I still have to either render or Material Manager->Apply to get the material changes to show in the View.

How do I do that, please?

Seems that I needed this as well:

  
          ....  
          aliastrans->Translate(TRUE);  
          for (LONG i = 0; i < count; i++)  
          {  
               dmat =          static_cast<Material*>(matArray->GetIndex(i));  
               dttag =          static_cast<TextureTag*>(tagArray->GetIndex(i));  
               dttag->SetMaterial(dmat);  
               dmat->Update(TRUE, TRUE);

               dttag->Message(MSG_UPDATE);  
               dobj->Message(MSG_UPDATE);  
          }  
          ...

The worst part is that there is no example of using CopyTo() with Materials. They neglect the little bit about needing to relink them in the Texture tag and I still don't know why the Object needs to be updated - but heck, it works.
