Haven't read through all the answers, sorry. Maybe i am a little redundant now. Materials. Pro simply looses the path to the textures and show a black sphere therefore. Edit the material and show Pro where on your hard disk the textures are. Thats it. Old objects. It is not a question of you not having used an older Vue version than 4. The downloaded old objects were created in Vue 3 or even in 2. Thats why they are old! :-)) Because Pro has a slightly different file format they need to be converted. Pro only has a built in converter for 4. The trick is, as for Mac users too, load the old objects into Vue d'Esprit 4 (on windows) and simply save them again. Then Pro is happy again.
