It would be cool to be able to import .PNG images and place them on a surface into the world. With basic options to resize and rotate. This could really help with storytelling. Examples: adding blood splatter, cobwebs, bones, cracks into a room. Adding wanted posters on the wall. Adding a portrait of the enemy in a home. This can be an easy way to age a building, or make it spooky. Maybe allow .GIF so animated fireplaces and swirling pools can be added.
