For thoose who intend to use the model in other scenes: take a look to animation track that would need to be deactivated.
They are in 'visible in render' parameters, and in material track, that change material color from black to white, and visibility in editor and in render options in different frames to allow the rendering of the 3 previews.
You could get very close and hi detailed rendering from this model.
If you see so much polygons and vertex is cause in the scene there are 5 copies of the same iphone, cause i needed to act this way if i wanted to arrange things to automatically render those 3 images you see in preview.
One model has a boolean animated to activate and deactivate to allow white model to have his charatteristics holes upon the hear-speaker.
If you are happy of your purchase, please rate me, if not please let me know let's try to fix it.
