We look inside the folder and search for keywords. For example for the color map we look for the keywords below. If we find a texture that includes one of these keys we know there is a color texture. We do this step each surface type. (Displacement, Reflection, Bump, ect)
Now we know the textures and the next step is to add all the textures to the correct channel.
There is a “SeachValues” .txt file inside the plugin so you can adjust if needed.
