Default PBR Model

Last updated
This model represents a material that provides a more realistic quality to objects, using physically based rendering. It allows for selecting and editing:
Environment Mapping
Normal Mapping
Albedo Texture, Color, and Blending
Specular Color
as well as adjusting Metalicness, Shadow Senstivity, and Roughness.
All these Attributes are described in greater detail below.
This Attribute provides the Name of the Material as well as the Shading model type. It also sets the Alpha value if it is toggled on.
The Alpha channel is additional to the RGB channels and adds a kind of transparency to the object by mixing the background and foreground colors. For example, if the Alpha value is set to 0.5, then this would result in a 50% mix of the object and its background, providing a somewhat see-through quality.
This enables the user to set a Texture which reflects the environment around an Object, meaning that the Object reflects the surface surrounding it (whether that be the background, another Object, or both combined.).
U offset (deg) sets the beginning of the image of the provided Texture to be "delayed" in the x or direction, moving it from left to right. The resulting "cut off" piece wraps around to the start of the image.
A normal is a line perpendicular to the surface of some object. Normal mapping distorts these normals and simulates a surface with light and shadow, even if the object surface itself is flat. This is only possible with a light source. The Normal Map sets this surface and Use Normal Map toggles it on and off.
This enables the user to set a Texture which reflects the environment around an object, meaning that the object reflects the surface surrounding it (whether that be the background, another object, or both combined.).
V offset (deg) sets the beginning of the image of the provided Texture to be "delayed" in the y or direction, moving it from bottom to top. The resulting "cut off" piece wraps around to the start of the image.
Color of Albedo sets the base diffuse color of the model.
Texture takes any image to add any desired visual information.
Using Blending, the Texture and Color are combined. If Blending is set to 1 then 100% of the Texture is displayed on the Object. If 0.5, then it displays a 50/50 ratio of Texture and Color.
Specular is the point of reflection of the light source. Color sets the color of it.
Metallic determines how much the surface simulates a metal-like quality, appearing shinier and harder or rougher and duller.
Shadow sensitivity determines the percentage of influence by the shadow. For example, a 1 would set an Object's surface to completely black. 0.5 would mean that even if the Object is in shadow, it would still have 50% of its color.
Roughness determines how rough an object is, limiting or strengthening reflectivity.
