Tools 1 Quadrant for Light Objects

The Tools 1 (upper-left) quadrant for viewport lighting appears when a single light object is selected in the scene.

Interface

Ambient Only

When on, the light object affects only ambient light in viewports.

Affect Specular

When on, the light object affects specular color in viewports.

Affect Diffuse

When on, the light object affects diffuse color in viewports.

Cast Shadows

Turns on shadows for the light, for viewport display. This setting does not change the value of the light’s Shadows toggle, so it doesn’t affect the rendered scene.

Light On

Toggles whether the light is on or off.

Select Light Target

This option appears only if you have selected a target light. Choose it to select the light’s target and reposition it.
