Transparent .BLP and crazy textures

[Jinaya]

Can't quite figure out how to fix this, nor why it's even happening.

I added two tranparent .BLP to replace the Upper and Lower scalp of my original race (troll) so that there was no texture present on the horns of my Draenei. For some reason though, when I did this, it added a really weird "line-ish" texture to my character.

I've tried everything to remedy this, and I just can't quite get it to work out for me.

Anyone have any clue how to fix this?

Transparency and BLPs is tricky. Most converters don't handle it properly. Check out BLPConverter (from Curse gaming), and use the -r switch, which will force it to create the BLP file type the game expects for scalps (indexed with alpha). Or if you don't want to **** with it I've attached a few that I used to do the same thing you are looking for, but for Orcs (hopefully they are the same size).
