The bundle typically includes roughness, specularity, and even translucency (SSS) maps, ensuring the skin reacts realistically to light in engines like Unreal Engine 5, Arnold, or Marmoset Toolbag. 3. Technical Excellence for Production
Use the clean mesh as a collision model or a "naked" layer beneath clothing generators (like Marvelous Designer). The realistic displacement ensures that skin-tight clothing reacts to real muscle and bone landmarks.
