Explorer tree/right-click/add lights

The light settings allows for the manipulation of the different properties of lights. It contains settings for light type, direction, elevation, the color of the light

and whether or not the light will cast a shadow when it hits an object.

Name: The current name of the selected light. Can be changed by double clicking the name.

Enabled: Turns the light on or off.

Light type: Shows the type of the selected light (omni, sun, spot or flashlight), as well as its direction elevation and azimuth, all of which can be changed by modifying the values.

Azimuth: The angle of the light towards the north, south, east and west faces.

Color: Contains settings about the color and intensity of the light.

Cast Shadows: Turns on or off the lights ability to cast shadows when it hits an object. It is also possible to modify settings for the shadow, e.g. its resolution, size, distance from object, how many shadow maps it uses and the transparency of the shadow.

Shadow transparency: How shadows actually work.Changes how realistically semi-transparent shadows are rendered. Can be controlled via Scene properties/Global Illumination/Shadow transparency:

Shadow transparency menu can be found under Global Illumination.

Shadow maps: Increases realism by correctly adding real-time lights. Works only if OpenGL 3.0+ or necessary extensions are found.

Resolution: Changes the resolution of Shadow map

Shadow samples: Changes how soft the edge of the shadow is. Value can be 1 = sharp, 2, 4, 8 = blur

Image on the left: Shadow samples are set to 1 and on right the samples are 8, which creates more softer shadows. (Model is from Google 3D Warehouse. "HML_Block10" by Pepe)

Near (m): Near plane distance for generating Shadow maps. Greater value reduces shadow bias.

Far (m): Far plane distance for generating Shadow maps.
