Spotlight Settings

Power

A measure of the light flux emitted from a light source in a unit solid angle. It is also referred to as amplitude, perceived by the human eye as brightness.

Shadow smoothness

Increasing the softness of the shadow allows to adjust the transition tone between light receiving and non-receiving surfaces.

Sample count

Indicates at how many points the light will be calculated. It affects the quality of the edges of soft shadows.

Heading

It is the angle value made by the light source with the global x axis. Enter a positive value counterclockwise and a negative value counterclockwise. Its unit is degrees.

Pitch

You can change the direction of the spotlight by entering a value between 0-360 degrees.

Fall off start angle

It specifies the starting and ending angles of the light edges (the area where the light begins to darken) in spotlight.

 Example

The spot light source creates a circular illumination effect on the surface. When the darkening angle is increased by entering the properties, a larger area is illuminated, as seen in example 2.

Fall off end angle

In spotlight, it defines the boundaries of the light edges.

Elevation

The vertical position of the light source on the story plan is determined. The level where the light source will be at a height of m / cm or mm from the ground is defined.

Light no
