Taking a screenshot of my unreal engine scene and selling the image externally incurs a fee?

If I render a scene in unreal engine based on assets made in blender, then take a high res screenshot. Thereafter, putting up the screenshot to be sold as an image. Do I incur any liability of having to pay unreal engine the 5% royalty fee after my first 3k earned quarterly? (Though highly unlikely an image would earn me that much :D)
Thanks

There is no royalty on revenue from a still image created with the engine.

Thanks You!
