Controlling the refection sharpness
When working with Lumion's materials, we have the option to control how sharp the
reflections are with the aid of the Glossiness slider. Usually, the glossiness texture
defines the uniformity of the surface in terms of visible texture and defects and this
can create a very shiny surface with sharp reflections or a blurry reflection, as shown
in the following screenshot:
This setting is useful when we want to create a material for a 3D model and show
that the object is new, or create a material for a 3D model and show that the object
has some age to it. Two more settings that are worth mentioning in this menu are
Saturation and Emissiveness .
Saturation
Saturation is a uniform increase in the intensity of all colors in the material. This
can result in oversaturation of certain colors, resulting in loss of details in those
areas, leaving them looking too orange and unnatural. On the other hand, when we
decrease the saturation, we will transform the texture used into a grayscale texture.
In some situations, a texture may look dull because of the light used or because of
other aspects, but a small increment of the Saturation setting will help to bring out
the colors again. Finally, there is another useful setting when working with lamps
and other sorts of lighting objects.
Emissiveness
The best way to understand what this setting does is to have a go and increase the
Emissiveness slider to the 100 value. The concrete material that we have been using
is glowing, but certainly, this is something we don't desire for a concrete material.
Is there any useful application?
