What are Scene Capture options in Blueprint Component drop-down and how are they used?

In BluePrints Component ,there are two stuff:
Scene Capture 2D & Scene Capture Cube

What are they and how to use?

Hey Tiny,

Scene Capture component acts as a camera in your level. It captures pixels it can see and translates that to a texture. You can see a working example of this in Blueprint Office project, downloadable for free from Marketplace, and read about how it works here:

Blueprint you’ll want to look for in that project to see how Scene Capture components transfer data to a material is BP_Security_Monitor. components themselves are in BP_Security_Camera_Tracking. Take a look and experiment with them!

Hope that helps!
