Sandy 3D, Не могу справиться с MovieMaterial

[unused_name]

Пытаюсь сделать простую вещь, изменить один из примеров с оф. сайта Sandy 3D поставив вместо битмап-текстур свои мувиклипы:

		}
	}
}

Флэш выдает:

TypeError: Error #1009: Не удается вызвать свойство или метод со ссылкой на объект "null".

at index()

Думаю я упускаю что-то простое и очевидное для программиста, но будучи дизигнером в упор не вижу в чем проблема, научный тык и гугление пока не помогли, помогите люди добрые, ткните носом

Добавлено через 5 минут
UPD: Уточню что именно я менял: добавил импорт недостающих классов sandy из примера с клипами, добавил функцию loadSideMovies(), задал материалы так:

var SideMat0:MovieMaterial = new MovieMaterial( queue.data["side0"],40 );

, назначил материалы поверхностям.
