FS2004 Removing shadows

Hello i'm sorry if this topic was covered before, if so, i couldn't find it.
I would like to know what parameters should i put to remove shadows of a .mdl object... Till now i have used parameters only for DUSK/DAWN/NIGHT/DAY configs.. Is it possible to remove shadows too?
Ok i realised that the correct way should be removing the shadows with mdltweaker and then place the object with obplacer....
