Shaders (Immersive Engineering)

Shaders are special upgrades added by Immersive Engineering for the Revolver (and possibly other items in future versions). They are applied in the Engineer's Workbench, inside the special Shaders slot. Shaders only modify the appearance of the Revolver; they do not added any additional functionality.

Shaders are obtained by trading with an Engineer Villager for 3-8 Emeralds.

Minecarts
Shaders can by applied to Minecarts by right-clicking a Shader onto a Minecart.

Chemical Throwers
Shaders can by applied to Chemical Throwers in the Engineer's Workbench.
