Почему не отображаются материалы и свет? Выполнение того же самого с «POST_VIEW» показывает правильный вид (материал, рендеринг), но без линий и прямоугольников. В документации указано только:

Обычно POST_PIXEL для 2D-рисунков и POST_VIEW для 3D-рисунков. В некоторых случаях можно использовать PRE_VIEW. BACKDROP можно использовать для фона в редакторе узлов. (types.py)

Как настроить сцену (кроме освещения)? Как это должно выглядеть:
