Paper 2D Blueprint Thumbnail
I've been following this tutorial, but the thumbnails for my blueprints that use paper sprite components don't show up. I'm having this issue with PaperSpriteActor blueprints and PaperFlipbookActor blueprints.
I have real-time thumbnails enabled and I'm using version 4.7.3 of the engine.
Open the Blueprint in which the thumbnail is not being displayed correctly. Go into the Viewport and re-position the camera to a good angle (the default angle is for +X and so the sprites will be viewed along the thin side and invisible). After re-positioning the camera your thumbnails should update to match IIRC.
Let me know if this worked for you, or if you are still having trouble.
