Phong - creates a Truelight Phong Material. The
Phong material uses the Phong shading algorithm.
Diffuse Color - sets the shader`s diffuse
reflection color. This is the color the shader will
adopt, when the light reflection of the surface
is spread to a brought range of directions.
Specular Color - sets the shader`s color for
specular reflection.
Specular reflection behavior is described by the
law of reflection which states that the direction
of incoming light (the incident ray), and the
direction of outgoing light reflected (the
reflected ray) make the same angle with
respect to the surface normal, thus the angle of
incidence equals the angle of reflection.
Roughness - the Roughness parameter defines
the amount of diffuse reflection and, its
complement specular reflection. The higher the
roughness value, the more diffuse reflection
will be rendered.
Color Texture
Use Texture - loads an image texture for the
diffuse color channel. The image will be used
as a pattern on the surfaces. Read
MaterialEditor -> Textures for texture
placement.
Use Alpha Channel - uses the alpha channel
of the image texture if it has an alpha channel
embedded.
Repeat mode - sets the repeat mode of the
texture. There are four modes, which can be
set.
Repeat - the texture will be repeated in all
directions.
Repeat Mirror - the texture will be repeated
and mirrored in x- and y-axis on every
repetition.
Decal - the texture will not be repeated.
Clamp - not the whole texture will be repeated. Only the last pixel of the texture will be
repeated.
Anisotrophy - sets the texture filter quality for the image texture. 1 is lowest quality. 16 is
highest quality.
Input Gamma - sets the texture image gamma correction.
