Learn how to create and edit a light entity.
The Light entity works like a ball or a beam of light. It can be used to add local lighting effects or spotlights to an area. This page covers the basics of light entities.
Go to Create and click on the Light icon to create a light entity.
A Light entity appears as an orange spherical grid. If you don't see the orange lines, you may need to select the entity and reposition yourself to see the entire entity.
You won't see any light unless there is an entity to reflect the light. In the image below, the Light entity has been edited to increase the intensity and has been positioned so that the light will reflect off a Box entity.
By default, Light entities cannot be selected for editing nor will they be visible to select.

This type of light is a point light and it emanates in all directions equally. It is meant for general area lighting as it has a bright point in the middle and fades as it radiates out.
To edit the Light to be a pink spotlight, complete these steps:
The domain sun shines from one side, so one side of the wall is already bright. Light from the Light entity won't show up on the bright side of the wall.
