I have set it to the correct SDK now, thank you for that.

I won't be using the Poser shader tree either, can't get it to work at all. 

The dynamic dress still disappears, but only when I import the whole scene. When I import only the little girl and the dress, the dress comes in correctly. Strange. Perhaps I should split the scene into parts and import them one by one.

Another baffling thing relates to the textures on the girl. In Vue's preview, they look correct. When I render a preview, the UV mapping is all messed up. I am so confused. Should the texture mapping be "automatic" or "automatic UV" or something else?
