Invisible transition mask
Maybe two days I am trying to make invisible transition mask, but without any success. :/
I need something like this what is shown on my GIF, but without white color (specific object will be slowly hiding under invisible transition, but for example background or some another specifics objects won´t be affected): 
If you have not understood exactly what I need, please write reply and I will clarify everything.
Please do you have some ideas, how I can achive it?
Thank you very much!
