I figured it out XD open the material file and under mane add :
material preset_(number)_equipMat ^^ then add R or L for which wing you want to use. Then just fallow the normal pattern like this :
material preset_3_equipMatL
{
technique
{
pass
{
texture_unit
{
texture(what you named it)_Left.png
}
}
}
^^ Hope this helps!
