Fade cloudy plastic animation

[PeterSwift]

Has anyone done a fade animation on cloudy plastic?  I can't get it to work correctly.
Keyshot doesn't seem to be able to fade cloudy plastic at all.  it just makes it opaque until the fade animation is over then it shows it correctly.
attaching a test render video, and the keyshot file in link.

Quite stressfull with a deadline
Does anyone have a workaround?

what render mode are you in, there was another person that was having issues with interior mode and animation fades.

just "normal mode"
It's send to the keyshot team and they are working on fixing the bug.
Still have not found a work around so I needed to change my animation, luckily it work decently.
