Thanks heartless. That may be the way the model comes into Blender as each element has its own map. If I do not combine the meshes in the model it renders like this in blender.
I thought at first there were only 8 maps listed when I ctrl-joined the model but that is only because only 8 can fit in the information window.
There are actually hundreds of maps! Each rafter for example has its own map, the door trim and each door panel etc.
This is a small house I am using to figure out a workflow to export from VW into UE4. The actual model I am trying to archviz is 10,000sf and far more complex. It would be impractical to try to map each item.
Lumion has got this stuff scripted pretty well in their system, they are basically a similar gaming engine so I figured it shouldn’t be that impossible. So I was encouraged when I saw 's project. Can’t imagine he re mapped each object. (?)
