I see, so the robot (or any other characterset) can be used as a tile or tileset in Tiled, right? It’s probably difficult to make that work properly in this case, because some of my charactersets don’t fit the standard grid option and were not drawn in a 48x48px grid or a grid divisible by 48. Can the purple selection in your screen/the tile selection in Tiled be set to a custom size? If not, I can only recommend to place charactersets (which don‘t use 48px formats like the ad robot) as events within RPG Maker/engine you use. In this case it seems some of my charactersets (mostly objects, probably) won‘t work with Tiled, unfortunately.
