Invisble Model? PLZ HELP Warcraft

[HELPME]

ok, this is what i did.
I extracted the model (NagaMedusa) to my warcraft folder and named it NagaMedusa and the models were there,
I imported the model to my map and named it NagaMedusa\NagaMedusa.mdx and his btn is Textures\NagaMedusa.blp
And the BTN works fine but the model shows a shadow.
PLS HELP ME IF U DO, IL GIVE U A BIGG THANK YOU

shadows i dont know, must have somethign to do with how the unit was created, their is a catigory on some building that change shadows... maybe theirs a setting you can change on the unit or perhaps a special effects trigger...
