I want to blend a detail tiled map for scratches. I don’t know how to setup my texture properly so that I can only get the scratches details. Right now when I blend my main diffuse texture with my scratches texture, It kinda blends properly, using an overlay node, but it also blends some white color information with it. What would be the proper setup for my scratches texture and my material in order to blend only the scratches and not anything around it (Photoshop setup as well, I’m using PNG - 8 Bit). I use a mask that I paint inside unreal to determine where the scratches will be visible on the model.
I’d appreciate if someone could post a material setup screenshot for achieving this (and also the PNG or other format setup in Photoshop). I blend my color map with the scratches color map but I don’t get the result I want. I’d like to only get the dark information from the scratches texture, and not the white. I have tried most of the blend nodes, and none of them gives me the result I want.
This is the result I get, with the white information that I want to get rid of (I only want the scratches, black color, and not the white around it) - The issue is less visible where the color of my model matches the texture color I use for the scratches. On darker colors, it’s more visible.
