Fade animation is not working

[eduardo.fuentevilla.blanco]

I have tried to make an animation using Inventor 2016 but the fade option does not work properly. The objects do not dissappear completely, there are like shadows instead. I have updated the newest vesion but it is still happening. I attach a video where you can see my problem.

You didn't attach a video, but I think I know where you are talking about. While making an animation with inventor 2015 I noticed that the fade option is not controlling the visibility but the transparency. When you render an animation with the shaded with edges option, the edges remain visible. Do's this sound familiar? Rob.

I think that is not problem. The thing is that with some objects the fade animation is working okay but not with others. I cannot attack videos so I send a image.
