Blurs the reflections seen in this material, and any refractions caused by ray-traced transparency. Useful for simulating
materials that are reflective or transparent but do not have a perfectly smooth surface, such as sandblasted glass or metal.
Surface roughness
Increase this value to make reflections and refractions more blurred. A value of 0 will not blur ray tracing effects at all.
Note
The quality of the blurred reflections and refractions are determined by the Accuracy Level of the current Ray Trace Quality Preset.
