Im trying to overlay these white markings as a PNG layer over the material i already have, but it gives it a white tint.
here are two examples, the left one has only the areas with texture using the PNG material and the rest has the base material, so you can clearly see the diference. the one on the left is completly using the PNG layer wich has the base material integrated into it on both.
im sure im just missing some node to tell the alpha channel to do nothing, but i dont know how to do such thing right now.
