Where you tell node wrangler what’ file names to look for…
I typed in the word roughness and it didn’t get it
I added a principal textured setup and the roughness map wasn’t added
The normal map was named the same as the roughness map was ie “normal” and “roughness” were the suffixes…and it got that…
all the textures that I tried to add to the principal texture setup had a _before the normal for instance and a _ after where it says normal or a _before where it says roughness and a _ after where it says roughness
it got the normal map and every other texture but it just didn’t get the roughness map be them pace that the word roughness from the file name into the node wrangler text box where you add the possible file
