Gaps between faces when exporting to Unity

[Intensegamer3]

Been having this issue in ArmorPaint where between the faces meet the color is the same as the base map background or the emission map even though the emission map is black there. The way I've solved it so far is to make the base map background the same color as the main color of the object but I can't do that for more complex models or if I have an emission material, is there any way to fix this in ArmorPaint?

(Don't mind the checkered look, this is just an example model I painted really quickly to show the issue)
