Hi there

I would suggest export Mars Habitat from DS to Poser as OBJ,I've tried few props from Stonemason to export as OBJ and all of them has worked for me This Mars Habitat I've and tried to export as OBJ and everything has worked although Skydome doesn't work for me with Superfly,but with Firefly I didn't tried at all

Hope this helps

Thanks,Jura
