Hello. I finally got shadows working and looking the way i want. They will be in the next update of Dungeon Maker Sketch which should be out in the next couple of weeks. I have a decent amount of things to get done on my list for the update and i think it will improve the software alot.

Used Paint.NET to add colour and a background to the black and white exported image to make this. It probably took around 40 minutes to colour and edit so not an easy task but it gives you an idea of the sort of things you can do with Dungeon Maker Sketch
