Arma 3 texturing artifact
So i do armour Retextures for Arma 3 and when i do i have this brighter version of th ebase texture that when ive painted on the Armour i duplicate the layer then put that underneath the painted layer to make the colours match with other assets we use from a different mod.
the problem is that sometimes this leaves this white line on the borders between different colours


Any clue how i might solve this?
my skills in SPP are very limited as i only do retextures of an existing texture
