NEED HELP! Lua Code problem! Adding color to item!

Okay so I added these wings to my server for pointshop (link): http://steamcommunity.com/sharedfiles/filedetails/?id=107165776 The white ones (default) work just fine but now I’m trying to make a second one with the black wings but I have no idea how change my lua code to get them to be the black ones they just keep loading as the default please help me! :3

here is my code for these wings:

ITEM.Name = ‘Wings’
ITEM.Price = 240000
ITEM.Model = ‘models/wings/wings_folded.mdl’
ITEM.Bone = ‘ValveBiped.Bip01_Spine2’
function ITEM:OnEquip(ply, modifications)
ply:PS_AddClientsideModel(self.ID)
end

function ITEM:OnHolster(ply)
ply:PS_RemoveClientsideModel(self.ID)
end

function ITEM:ModifyClientsideModel(ply, model, pos, ang)
model:SetModelScale(1, 0)
pos = pos + (ang:Right() * -5) + (ang:Up() * 2) + (ang:Forward() * -48)
ang:RotateAroundAxis(ang:Right(), 270)
ang:RotateAroundAxis(ang:Up(), 90)
ang:RotateAroundAxis(ang:Forward(), 3)

return model, pos, ang

end

if SERVER then
resource.AddFile( “materials/models/wings/blackwings.vtf” )
resource.AddFile( “materials/models/wings/blackwings.vmt” )
end

All of the models and materials are in the right place!

This is the code for a pointshop. If you wanted to change the color of the wings I’m sure you’d have to edit one of the material files

The only material files are for the black wings… there must be some code that adds .vtf’s and .vmts
