Player model shine

Does anyone know what files may cause a shine/sweaty look on some player models? It seems to be mainly on older player models, but I also noticed that it affects Corey Kispert's hair as well. I'm just curious to know if there's a specific file or line of text in another file that causes this. I'm fairly new to modding and it was something I noticed while working on some things.

Some examples:

That´s the bentnormal map: face_bentnormal_o.xxxxxx.dds

Thanks for the help, but I'm not sure that's right. Changing the face.iff, but keeping the same png.iff keeps the same shine on the model.

Are you using any modded global?

Nope. It's interesting as well that the shine on the Kispert model only affects the hair, even if you change the hair model to a different hair model the new model will still be shiny. Very strange haha.

I had the same issue with Jaylen Brown, found out its the "hair__.fx.tweakabl;es". take that out and the hair will get rid of that shine. (also beard tweakables does the same for facial hair)

So I'm not 100% sure if this is what you're talking about as it doesn't pertain to hair but when it comes to the shine on the skin of the models, I found that adding/adjusting the following lines in the appearance.rdat file makes a huge difference:

"noise uv scale": 31.855,
"pore tiling": "REGULAR",
"min roughness": 0.324,
"max roughness": 0.73,

Some of the older players and converted models don't even have that info in their appearance file. Adding it seems to help quite a bit in my experiences.

Also, there's also a specific adjustment that can be made in the face color texture file that applies specifically to the face file.

this is really late but i just remembered that i found out the actual answer hair shiny-ness so if anyone comes across this it hopefully can help - you have to invert the hair_tangent.dds. I use photoshop for texturing but i assume it the same as other programs. you just ctrl +i or go to image ->adjustments -> invert.
so instead of the pink and purple colors, the inverted green and blue colors should give a much flatter look to hair.
And make sure to save it correctly in "BC7_UNORM" (alpha).
