由于材质在发光,所以 自发光颜色(Emissive Color) 输入将控制材质的哪些部分会发光。理想情况下这将获得一个遮罩纹理(除了需要发光的区域之外,大部分呈黑色)。
由于支持HDR光照,所以允许大于1的值。
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.
