if(object.shadowCameraLeft !== undefined) {
                methods.opValI(9,{name:'Sh Cam Left',value:object.shadowCameraLeft,step:10,fix:'2'},op,function(v){
                    object.shadowCameraLeft = v; // Trying to change
                });
            }

            if(object.shadowCameraRight !== undefined) {
                methods.opValI(9,{name:'Sh Cam Right',value:object.shadowCameraRight,step:10,fix:'2'},op,function(v){
                    object.shadowCameraRight = v; // Trying to change
                });
            }

object.shadowCameraLeft = v; // Trying to change
object.shadowCameraRight = v; // Trying to change
