So this is the problem that I found. When I add Normal map to model in Smash Forge and mod into the game, the normal map didn't show up in Game and there is the red texture show up. (I didn't add that red texture in Forge)
This is what Normal map look like.
This is Diffuse map.
What do I have to do in Forge to make normal map appear in Game ?
And... Do I have to use all of these texture in folder that I got ? [ I also don't know what that black map & blue-green-pink map (MRA) are for. ]
