Iris Shaders Mod For Minecraft 1.20.4, 1.20.1, 1.19.4
Iris 1.20.4-1.20.1 is one of the first Fabric shaders that work on a simplified and more advanced JSON programming language. In addition to more advanced features than JavaScript, this language is compatible with most optimizing modifications, which gives the player a beautiful picture and FPS boost at the same time.

As you know, Optifine HD is also moving towards the implementation of JSON, but sometimes it takes more time for the author to update his project simultaneously for both JS and JSON. To do this, there are separate optimizers or boosters that can be updated quickly and so you can improve vanilla graffiti almost immediately after updating the game.

In our case, we will consider Sodium, which is a very large project that has hundreds of features to independently update and optimize graphic elements and also work together with additional shaders.
Iris mainly focuses on Sodium, because shader scripts have “Class” parameters and can change dynamically (For example, microelements random in size and speed of movement). In front of the screen, the player can have thousands of such microelements and this loads both the processor and the video card very much. Sodium will be able to divide such elements into clusters and modules to create instead of one queue of thousands of elements – there will be hundreds of queues of only 10 elements, which makes drawing instantaneous and with minimal lags.

Iris harnesses the full potential of JSON classes, revolutionizing the visual landscape of Minecraft. With this innovative approach, it’s now possible to create new layers that seamlessly interact with existing ones, introducing a level of depth and intricacy never seen before. Experience the magic of beautiful rainbows that redefine realism, as Iris crafts them with a fresh perspective.

Dynamic shadows add another layer of immersion to the game. The sun’s shadow is meticulously detailed and dark, providing a stark contrast to the softer, blurred shadows cast by torches and other dim light sources. This nuanced play of light and shadow enhances the overall visual experience, making each in-game moment more captivating.

Ender World, in particular, stands as a testament to Iris’s capabilities. Prepare to be astonished as you explore this dimension, now adorned with an abundance of 3D clouds and a myriad of captivating microparticles. The attention to detail is unparalleled, creating an atmosphere that captivates any player who ventures into its depths.

Moreover, Iris introduces improved physics for water, elevating aquatic environments to a new level of realism. Dive into the game, and you’ll notice an underwater camera effect that dynamically distorts visible light, giving rise to captivating reverse waves. These subtle yet impactful features enhance the immersive quality of Minecraft, transforming the familiar into a visually stunning and dynamic realm. Explore the vast possibilities Iris has to offer, and let your Minecraft experience transcend the ordinary.
