Lighting mode



The lighting mode determines the way light from all sources renders in the World. It is set from Terraria's settings menu, in the "video" sub-menu. There are four different lighting modes available, which can also be cycled during gameplay by pressing + key.

The lighting mode also dictates whether the game will utilize certain performance-intensive visual effects, like the smoothing of liquid flow, along with the following shader effects (most of which were introduced in 1.3):


 * The reddish lighting and vignette applied during a Blood Moon
 * The distortion effect around Celestial Towers
 * The heat distortion effect in the Desert and The Underworld
 * The amplified background dust effect seen during Sandstorms

The effects above will only be applied in the Color or White lighting modes, and are deactivated in Retro and Trippy modes.

The chosen lighting mode will have an effect on the performance of some computers. Refer to the table below for each mode's performance requirements (lower means better performance on worse computers).

Mode details
Color mode is the default. It determines light levels using pixel clusters that are smaller than tiles, which means that light transitions more smoothly. White mode does the same, but all light is white, regardless of the color of the source.

Retro mode renders light levels per-tile, producing a more "blocky" or "pixelated" look, and also renders all light as white-colored. This mode reproduces Terraria's look from before its 1.1 update. Trippy mode does the same, however, allows colored light, whose colors are similarly determined per-tile.
