此示例显示了 软源半径（Soft Source Radius） 对光反射的影响。软源半径（Soft Source Radius）位于 细节（Details） 面板的"光源（Light）"类别下。
软源半径（Soft Source Radius）是一种模糊淡出您认为过于鲜明的高亮部分的方式。通常，使用材质本身的粗糙度值或纹理是个不错的主意，这样做就无需在光源上设置软光源半径（Soft Source Radius），但后者对于偶尔的杂散光非常有用，因为杂散的高亮部分过于鲜明。还必须注意，将该值设置为大于1的值会使光源在物理上不正确。
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.
