Screen Space Reflections
The Screen Space Reflection effect creates subtle reflections that simulate wet floor surfaces or puddles. Screen Space Reflection is an ideal effect to limit the amount of specular light leaking. For further information on the Screen Space Reflection effect see the Screen Space Reflection documentation in the Unity manual.
Properties
| Property | Function |
|---|---|
| Preset | Select the quality preset from the dropdown. Use Custom to fine tune the quality. |
Maximum Iteration Count (Custom preset only) |
Set the maximum number of steps in the raymarching pass. Higher values mean more reflections. |
Thickness (Custom preset only) |
Set the value of the Ray thickness. Lower values are more resource-intensive but detect smaller details. |
Resolution (Custom preset only) |
Select the size of the internal buffer. Select Downsample to maximize performance. Supersample is slower but produces higher quality results. |
| Maximum March Distance | Set the maximum distance to traverse in the scene after which it will stop drawing reflections. |
| Distance Fade | Set the value for the distance to fade reflections close to the near plane. This is useful to hide common artifacts. |
| Vignette | Select the value to fade reflections close to the screen edges. |
Performances
Only use the Custom preset for beauty shots. If you are developing for consoles, use Medium as the maximum, unless you have plenty of GPU time to spare. On lower resolutions you can boost the quality preset and get similar timings with a higher visual quality.
