Ответ: Тени (Xors3d)
|
Насколько мне известно, эффект надо применять на каждый чайлд

Об этом я знаю , я так иделаю . Но вот когда чайлдов много , то при запуске - "долго думается" , а потом вылетает ошибка . Вот мне интересно , почему ?

В чем проблема подскажите , пожалуйста .
И еще просьба . Дайте ,пожалуйста, кто-нибудь пример паралакса .
