Model Scaling causes Transperant effect

[Lindsey]

I'm making an Endor map (I know, nuthin new)

 

I used GTK's Tree planter to add some neat look pine trees, and then used model scale to up the size to ten (ten times the size)

 

The trees look like they should look in endor, but theres a ghosting effect with them, Sith J Cull says the shaders being streched, is there anyway to fix the transperant effect?
