Do you know, that… ?
By making renderings, depending on the selected scene, the model will reflect the environment – that is it, what surrounds him. Even the standard scenes included with the program give great opportunities to obtain realistic effects.
But apart from the scenery, the optical properties of the appearances are also important. Brushed metal will react differently to the environment, or a shiny material.
There is, however, a setting, allowing you to control the quality of the reflection, more specifically, smudging.
In editing the appearance it should be on the tab Advanced choose Illumination. There one option is Blurry Reflections, which should be selected.
After rendering, the reflections are blurred, not clearly outlined as before.
