Shaders (Immersive Engineering)

Shaders are special upgrades added by Immersive Engineering for various items. They are applied in the Engineer's Workbench, inside the special Shaders slot. Shaders only modify the appearance of the Revolver; they do not add any additional functionality.

Levels
Shaders have four different levels, or six before 0.8. Higher levels are more difficult to obtain.
 * 1) Common
 * 2) Uncommon
 * 3) Rare
 * 4) Epic
 * 5) Relic (Removed in 0.8+ because it is unused)
 * 6) Cosmic (Removed in 0.8+ because of no Avaritia update)

Levels do not have any differences directly, except for the Cosmic level, which cannot be applied to Balloons.
