Recently i noticed something, I'll need your help with.
I noticed that for blank objects, I mean fully transparent, used only for detecting collisions, on export i got black PNGs exported. For now I'm making them 2x2 pixels, and then scaling them to the right size. I wonder is there a way not to use maps at all, or all transparent objects to use only 1 map, 2x2 pixel?
And one more thing. Is there a way to make 2 or more different sprites to pack their maps in 1 atlas? I know if sprites are different animations or frames of a single sprite object, they'll pack, but can i do it with different sprites?
