Let's say I have two parts in the exact same spot. I want one to show from 0 to 10 secs and then be hidden and then the other part to show at 10 secs and stay showing until turned off.

If I hide the part that is supposed to be on at 10 secs it works from 0 to 10 secs. However if I move to 10.00001 secs and click show it now fades the part on for the first 10 secs. Not what I want. Seems no matter where I place keys I can only fade a part on and off not just turn it on and off.
