A Blender add-on for building tile based low-poly scenes with paint/map editor like tools · By Jeiel Aranal
Is it possible to paint tiles with alpha onto others, like a flyer tile on a wall tile? If not, do you consider adding something like that in the future?
It's a feature I want to have but I can't say when it would be implemented, I suspect it will take a bit of work because this will need to use a second UV layer.
Yeah, I can imagine the technical difficulties. Sprytile is a fantastic work anyway!
