[Question] Zhevra Mount Model Edit

[Ciris]

I'm using Glitchy's model editting suite, and I believe the Zhevra is classified under the unicorn, but when I select "Mount to change" as Unicorn, and put "Mount to Change to" as Frost Sabre and select "BLP to Use" as RidingTigerSkinNoStripeWhite, when I log into the game after putting the .MPQ into the Data folder, just plain Data, it doesn't seem to work, how can I fix this?

[Ciris]

Anyone? Or can anyone convert this for me please? Or tell me how to make it into something different? Maybe an Amani War Bear?
