Texture questİon !!!!!!!

I bought model.But texture wrote like that : Material_g Material_c Material_s What are these?

_g I don’t know what it could be other than global illumination…
_s might be specular map or subsurface profile map.
_c could be color, custom, clear coat, or cloth.

You should provide more info regarding the model and show the textures. Those could be anything, but most likely they’re outdated and not used by UE4.
