Where do you want to put the transition, you just need to divide the material and drag the transition to a separate place. You can adjust the internal parameters yourself and see the effect.

Generally, when you open a transition, there is a preset inside. Just double-click it. A single door is nothing more than scrolling pages left, right, up and down, and so on.
