I searched the forums, but could find nothing to help me with this problem.
I've created a new unit based the voltigeur using maxsim666's tutorial, and I've got it working correctly with the custom atlases I've made, but for some reason the faction colours are seriously faded---the diffuse and normal-map look correct, though.
Mine is on the left (the right is the default voltigeur, shown for reference).
The colours under the uniform_to_faction_colours are exactly the same as the voltigeur, and as far as I can tell, there is nothing wrong with the colour_mask atlas texture. It's not just pure grey, though; I tried changing the colours to bright red, and it turned a very faded red ingame.
Any and all help would be very much appreciated.
