反射

如果开启此效果,所有材质将使用深度缓存器和之前帧的颜色,来形成比反射探针更精准的反射效果。

If a Reflection Plane is near a reflective surface, it will be used as the source for tracing rays more efficiently and fix the partial visibility problem

However, the reflected color will not contain the following effects: Subsurface scattering, volumetrics, screen space reflections, screen space refractions.

折射
Screen space refractions work the same way as screen space reflections and use the same parameters. But they are not enabled by default on all surfaces. Enabling it will have a small performance cost. You need to enable them in Material Properties ‣ Options. Materials using screen space refractions will not be able to cast screen space reflections.
半分辨率追踪
使用半分辨率光线追踪。仅使用四分之一像素的光线。开启此选项将会降低质量,但可以大幅减少图像占用内存并提升性能表现。
追踪精度
提升光线追踪精度的同时会引起更多的噪点并降低最大追踪距离,另外也会增加性能开销。
厚度
在追踪过程中纳入深度缓存器内计算的像素的厚度。较高的数值将拉伸反射和增加闪烁。较低的数值可能导致光线丢失物体表面。
边缘衰减
反射的像素在靠近屏幕边缘的地方会平滑淡出。淡出的程度由像素位置所处的屏幕中心到边缘的百分比决定。
钳制
牵制反射颜色强度来移除噪点和闪烁。
