This is more of a nit pick, but as there are only so many material channels we can pass to Unreal, I am forced to use the emissive channel to pass my packed maps. Unfortunately it appears to be hard coded to default these maps to grayscale compression. This is an annoyance because I then have to manually go into individual textures and change this. And just in general there may be times users wish to use a colored emissive map. Hopefully this changes in the future.
