Hm. Make sure that you're using this code:
material preset_12_maneMat
{
technique
{
pass
{
cull_hardware none
cull_software none
alpha_rejection greater_equal 128
texture_unit
{
texture preset_12mane.png
}
}
}
}
on the mane section of the code, and be absolutely sure that you're saving it. If you're using this code, it should appear normal and not have that strange transparent-y effect with the default code. If you are using this code, and the mane file's name corresponds to the name in the code (and is a .png), it should work.
