The mod installs shaders in a Minecraft game and adds several graphic 3D drawing buffers, a map of shadows and reflections. These things can be used to change the appearance of the cubic universe, and how it will look depends on the selected shader package and some user settings. 
 

Add-ons GLSL Shaders will help the game Minecraft look very realistic, and this mod removes all unwanted objects and adds beautiful graphics, making it more exciting.

If you look at other realistic shaders for Minecraft, then the GLSL Shaders mod contains many other packages assembled, ensuring that the player finds a redesign of a familiar object each time the game is loaded. 

Using the collaboration of several mod developers, mod shaders provide graphic changes to shadows, weather, light, and drawing maps, and although these aspects seem simple enough, they change most of the visual atmosphere of the game. 

Now the stormy weather will become darker and more sinister, the sunlight will become brighter and more soothing, and the sunsets will look more gorgeous than before.

The developer of Sp614x combined two functions and created the Optifine HD mod with a new addition to the shaders, and for this you don’t need to add a separate mod, and just install the Optpine HD modification .

We strongly recommend that you take a look at the page we suggest in order to choose an additional shader pack to create optimal perfection in cubic visualization of special effects.
