Could very well be your blend mode is off on the mane. Try using this:
Just replace the mane material section
material preset_#_maneMat
{
technique
{
pass
{
cull_hardware none
cull_software none
alpha_rejection greater_equal 128
texture_unit
{
texture preset_#mane.png
}
}
}
}
Replace the #s with the preset folder number of course.
