Hi guys, I have 1 model (object) and it has 3 txd,3 dff and 2 col files

How I can for 1 id (for example 2086) set this object?

I tried this,but it doesn't work:
 

txd = engineLoadTXD ( "c1.txd" ) 
engineImportTXD ( txd,    2086 ) 
txd2 = engineLoadTXD ( "c2.txd" ) 
engineImportTXD ( txd2,    2086 ) 
txd3 = engineLoadTXD ( "c3.txd" ) 
engineImportTXD ( txd3,    2086 ) 
col = engineLoadCOL ( "c5.col" ) 
engineReplaceCOL ( col,   2086 ) 
col2 = engineLoadCOL ( "c7.col" ) 
engineReplaceCOL ( col2,   2086 ) 
dff = engineLoadDFF ( "c4.dff", 0 )
engineReplaceModel ( dff, 2086 )
dff2 = engineLoadDFF ( "c6.dff", 0 )
engineReplaceModel ( dff2, 2086 )
dff3 = engineLoadDFF ( "c8.dff", 0 )
engineReplaceModel ( dff3, 2086 )
engineSetModelLODDistance(2086, 160)

Help pleasee:(
