Hey I had something in the working: I would have called it "Cut Kit" but it is far from finished! But hey I thought I simply share these screenshots (bad tutorials) here with all of you.  I will try to explain these techniques. 1. Fade between scenes. 2. Blendo Style Hard Cuts

So the event I am calling it from is the left mouse button (for testing). All these blueprints are in the first person character (the generic one)

Hard Cuts: 

1. The logic behind it is: move camera to 0,0,0, so we can simply add the pitch/ Yaw.  As the camera is controlled through the controller we must take the same way. It is the same logic behind just looking around. Warning these controls have a scale applied to it (ex 1.7) and so you will want to divide it with the rotation you need. 
2. You get that out of the Find Look at Rotation (divide it with the scale).
3.  Then you add it to the controller
4. The camera moves

Fade to Scene: For the fading scene we need to add something to the first person character blueprint: A Capture Component 2D. It should have the same settings (example: film grain, Lut).  It should capture the entire screen. You can think of a Capture Component 2D as a camera. Now to the blueprint

1. So we create the Render Texture with the right settings 
2. We apply the Render Texture to the UMG (the render texture will be the image on the box that fills the entire screen) (for easy communication we use game instances (https://www.youtube.com/watch?v=5w594D3qtLs&t=19s)
3. We simply apply it to the viewport. (You could also set it to a loading screen when you change the level)( You can have it animated in the UMG (ue4 Unit))

So I hope this is helpful. If you've got any questions, then please reach out to me. I will try to answer them. Good luck with these blueprints
