A ‘Flip Book’ node in UE4 is the way to create an animated texture using a Sprite-Sheet.
Its very simple to use:

  1. Import a Sprite Sheet texture containing the animation frames.
  2. In the UE4 Material, Create a Texture Object node, and set it’s Texture property to be the Sprite Sheet texture you imported.
  3. Create a Flip Book node and connect the Texture Object Node to its  Texture input.
  4. Connect numeric value constants to the Flip Book node’s Number of Rows and Number of Columns inputs to set the layout of the Sprite Sheet.
  5. Connect the outputs of the Flip Book node to the wanted material inputs.

The following example shows a way to create a custom Flip Book material to animate textures.
Q: Why would you do that???
A:
Well the truth is I created it without knowing there is a built-in option, and found out about the Flip Book node right after I finished my own.. 😀
But it’s also a useful example of locating tile coordinates within a plane..
