Need help identifying texturemaps for Berserk Warriors

Kuroyasviel

there is no prefixes for this maps so me and a few people are lost.
one of the seperate maps.

This map is stored in the diffuses alpha.

Here is the character these textures go to. I left out the diffuse and normals on purpose since we figured what they where.

Any help is appreciated!

Kinda hard to tell but they could be oldschool spec and gloss maps.

When the second map is curved in photoshop, it actually does give off a kind of specular look but it doesnt work well, and would a game released in 2016-17 use old school speculars?

I watched some blurry videos on youtube, so it's hard to tell if anything super fancy is going on. Some model parts seem to have stronger shading at extreme angles than others, like homeboy's chin seems to get a nice outline regardless of angle, but less so on his outer forearms.

Looks like old school specular, and alpha test.

Kuroyasviel

Would there be any way to convert the old school specular into regular specular? And the second map that includes alpha test can be curved into either to look kinda like specular [not sure what would be proper for this] and an actual alphatest.


Metallics seem to look great in musou

On second thought, is there a chance the textures were extracted improperly?

Obscura

Wait so in your original post, the second map is altered? First I also thought its for alpha test but it has those gray colors while for alpha test , you want a black and white texture. Unless you want to animate the cutout - threshold.

About converting the old spec map to a new:
 There is a great tutorial about converting old school spec into new school spec on Marmoset site.

Well, the 2nd map doesn't need to be edited to work with alpha test, which just applies a cutoff value so any pixels darker than that get cut away and any brighter become solid.

Without the shader though, you can't be sure how the maps were used. Can you extract a shader?
