omnidirectional light的意思|示意

You could model the previous bed scene with an ambient light to lighten up all objects to some degree and create an additional omnidirectional light.

您可以用环境光模拟前面的卧室场景，将所有对象都照亮到一定程度，从而提供了另外一个全向光源。

The ambient reflection only reacts to ambient light; thus, using an omnidirectional light has no effect.

环境反射仅对环境光起作用，因此，使用全向光是无效的。
