UE3 Textures

[RedBear]

Most likely DM is Diffuse map, NM is Normal map, SM is Specular map.

I have another question : so I got the thing with the Diffuse, Normal and Specular Maps textures. There is still one thing i'm not sure of : is the information about the transparency of the normal and specular maps stored somewhere in the UE3 files, or are they intrinsic? Meaning, are the textures made to be of the good transparency, or is it written somewhere else how transparent they're supposed to be?
There is a folder in the exported files named "MaterialInstanceConstant", containing a file named "WhiteKingBody_XXX_Mat_INST.props.txt". The content of said file is the following :

"Parent = None
ScalarParameterValues[3] =
{
    ScalarParameterValues[0] =
    {
        ParameterInfo =
        ParameterValue = 2
        ParameterName = SpecularPowerB
    }
    ScalarParameterValues[1] =
    {
        ParameterInfo =
        ParameterValue = 50
        ParameterName = SpecularPowerA
    }
    ScalarParameterValues[2] =
    {
        ParameterInfo =
        ParameterValue = 15
        ParameterName = SpecularColorAdd
    }
}
TextureParameterValues[3] =
{
    TextureParameterValues[0] =
    {
        ParameterInfo =
        ParameterValue = Texture2D'CH_WhiteKing.WhiteKingBody_NM'
        ParameterName = NormalMap
    }
    TextureParameterValues[1] =
    {
        ParameterInfo =
        ParameterValue = Texture2D'CH_WhiteKing.WhiteKingBody_SM'
        ParameterName = SpecularMap
    }
    TextureParameterValues[2] =
    {
        ParameterInfo =
        ParameterValue = Texture2D'CH_WhiteKing.WhiteKingBody_DM'
        ParameterName = DiffuseMap
    }
}
VectorParameterValues[3] =
{
    VectorParameterValues[0] =
    {
        ParameterInfo =
        ParameterValue = { R=0.116576, G=0.325037, B=0.796917, A=1 }
        ParameterName = TransmissionColor
    }
    VectorParameterValues[1] =
    {
        ParameterInfo =
        ParameterValue = { R=0.68002, G=0.579547, B=0.511398, A=1 }
        ParameterName = SpecularColorAreaB
    }
    VectorParameterValues[2] =
    {
        ParameterInfo =
        ParameterValue = { R=0.625345, G=0.409826, B=0.415148, A=1 }
        ParameterName = SpecularColorAreaA
    }
}
BasePropertyOverrides =
StaticParameters =
RuntimeVirtualTextureParameterValues[0] = {}
FontParameterValues[0] = {}
FlattenedTexture = None
MobileBaseTexture = None
MobileNormalTexture = None
bUseMobileSpecular = false
MobileSpecularPower = 16
MobileSpecularMask = MSM_Constant (0)
MobileMaskTexture = None
TextureStreamingData[0] = {} "
Is the info I'm searching after in these data? Is there a value (like "ParameterValue") that indicates, like, a percentage of transparency?
Thanks for your help in advance, sorry for the probably dumb question!
