The mat_NM is already assigned when you attached the action SpinMe to the entity of your choice.
You can also attach the DLight action to a dummy model if you like. Try:

Code:
//////////////////////////////////////////////////////////////
// carlevel main.c: Load level,init physics, do camera control
//////////////////////////////////////////////////////////////
#include <acknex.h>
#include <default.c>
#include "physics_car.c"  //  <--- that's where the magic happens
#include "startup01.c"   // splash screen
#include "cg_add.c"      // Czeslaw Gorski actions
#include "NM.c"
//////////////////////////////////////////////////////////////

var camera_arc=100;
//////////////////////////////////////////////////////////////

function start_all();
function zoom_cam();

// global vars
FONT* fontArial = "Arial#20b"; // truetype font
ENTITY* pFocus;					// camera will orbit around this entity
var temp[3];
var temp2[3];

Note: copy/paste the relevant code from NM.c to main.c, or clean the NM.c script before including it to the mainscript of the carlevel demo.
