Hi!

I am using the Hierarchy Class to walk through the Scene Hierarchy. I am trying to Export an object that has a Texture Tag applied, but when I iterate through the Tags, there is no Texture Tag. UVW and Phong Tags as well as two hidden Tags (Tpoint & Tpolygon) are there, but no Texture Tag.
Yes, the Material is applied to exactly the object I am looking at in the editor (it also shows up on that object when I call "Current State To Object" in the editor). Does the Hierarchy Class perhaps store Hierarchical Tags somewhere else?

Confirmed. I'm investigating why this is and if there's a workaround. I guess one possibility is to use SendModelingCommand() with CSTO and do the hierarchy traversal yourself.

Hi Mikael!

Thanks for the prompt reply. The problem is, that I need both, the original hierarchy and the hierarchy with the virtual objects at the same time and (more importantly) know in which relation they are standing (via, GetCacheParent()), so I can pick objects from both hiararchies. As far as I remember this doesn't work with SendModelingCommand, because the connections are gone, but I might be wrong here...
