Photometric light list

Photometric light sources installed in the project are listed.

3D preview

It is the front view of the light source. The dimensions of the type selected in the table above the relevant image in the image can be adjusted. You can rotate the image around itself by holding down the left mouse button and moving it. You can zoom in and out by holding the right mouse button and moving the mouse.

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.


By entering a value between 0-360 degrees, photometric light direction change is provided.


The vertical position of the light source on the floor 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

It can be named with the number given to the light source.

Sample count

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


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

Cast shadows

When the option is checked, shadows caused by the light source are shown.
