1.2 - 聚光源(1.2 - Spot Light)

聚光源 从锥形空间中单独的一个点散发光线。用户可使用两个锥体来塑造光线形态——内锥角外锥角。在内锥角中,光线达到最大亮度。当你从内半径范围移到外锥角范围时,发生衰减,形成半影,即在聚光源照明圆盘周围光线变柔和的情况。

在上图中,我们可以看到该聚光源的内锥角非常窄,而其外锥角则要宽得多。定义它们的方法是选中光源并转至 细节(Details) 面板。

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
