Easy fix! Go to your preset's material file, open it in notepad, scroll all the way down, and replace your mane code with this one here.
material preset_#_maneMat
{
technique
{
pass
{
cull_hardware none
cull_software none
alpha_rejection greater_equal 128
texture_unit
{
texture preset_#mane.png
}
}
}
}
Replace the "#" with your preset's number as well. Let me know if this worked!
