Here is an example of how Metallic is affected by Roughness. The more Roughness that is applied to the Material, the less shiny the Metallic will becomeĪnd the lack of Roughness will make the metal appear to be very shiny. The Shininess of Metallic objects is controlled by the Roughness. This is because the Roughness value is being slightly increased until it reaches a value of 1. The sphere on the far left has a Roughness value of 0, notice how well you can make out the reflections.Īs the spheres move toward the right, they become less and less shiny. Here is an example of how Roughness can affect Shininess. While the less rough a surface is, the more Shininess it will have. The more rough a surface is, the less Shininess it will have. Roughness plays a major role in helping to determine the Shininess of a surface. The less light a surface can reflect, the less shiny that surface is.Ī surface's ability to reflect light can be affected by all sorts of things in the environment from very small specs of dirt landing on the object to the oil on your hands rubbing off when you touch the object,Īll of this can affect a surface's ability to reflect light. The more light a surface can reflect, the more shiny that surface is. Shininess simply refers to a surface's ability to reflect light. In the following How - To, you will learn everything you need to know about how to introduce Shininess to your Materials. Inside of Unreal Engine 4, you can simulate the shininess of objects using Metallic, Specular, and Roughness Material inputs. Every object that you come into contact with everyday has some level of shininess to it.
