6.1 - 阴影偏差

此例展示了 阴影偏差。此属性的主要作用是让物体与表面结合得更好。但这也存在权衡,降低此值来让物体更贴地有时会引起自投射阴影瑕疵,如下图所示:

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.
