Again, it's my first time with materials. But this mat is shorter and it works. Is it wrong?

Well, it was about time I started with Materials anyway.. *goes studying*

Code:
material mtl_nolightmap
{
effect=
	"
	technique disable_lightmap
	{
		pass p0
		{
		    ColorOp[2] = Disable;		
		}
	}
	";
}
