CleanMode让用户可以轻松自定义的视窗种切换，默认会移除掉不被渲染的东西：例如样条线或者透视网格等，可以得到一个很干净的视窗，让你的场景的清晰视图元素。

CleanMode is a plugin designed to allow users to easily switch back and forth between Cinema 4D’s standard set of viewport filters to a second custom set.

The default behavior removes elements that will not render such as splines or the perspective grid, allowing a clear view of your scene.
