BLP won't be transparent

[pibesabe]

So, lots of blps have some transparent parts usually for team color, but for some reason working with a moonkin model i ported from wow, i can't make some of his textures transparent, his arm feathers and "beard" should have transparent parts. I tried making a almost 100% transparent blp and all it did was show as white (shown in photo).
How do i make it so that i can have some transparent parts?

Fixed it! You have to go into the model editor>Materials> And put the material in "blend" mode. This will fix it.
