+## blender_render_settings
+Сценарий настроек редактора Blender для уменьшения времени рендеринга.
+
+Тестовая сцена
+![](img/scene.blend "Тестовая сцена")
+
+Сценарий работает в 3х режимах оптимизации:
+- small
+- medium
+- large
+
+Время тестовой сцены по умолчанию - 32 сек.
+![](img/blender_render_settings_default.jpg "Время тестовой сцены по умолчанию")
+
+Время тестовой сцены в режиме `small` - 13 сек.
+![](img/blender_render_settings_small.jpg "Время тестовой сцены в режиме small")
+
+Время тестовой сцены в режиме `medium` - 10 сек.
+![](img/blender_render_settings_medium.jpg "Время тестовой сцены в режиме medium")
+
+Время тестовой сцены в режиме `large` - 4 сек.
