Iris Shaders is one of the most popular mods for installing and using shaders in Minecraft 1.21.5. It features a user-friendly interface, and when paired with mods like Distant Horizons, it is a popular choice for casual hobbyists and hardcore modpack builders.

Head to the official Iris Shaders website and download the universal JAR for Iris Shaders. Run the JAR and make sure to select 1.21.5 as the version. If you have Fabric 1.21.5 installed, you can skip the installation of Iris+Fabric. However, if you do not have the mod, you can download the combination.

Before you proceed, make sure the installation directory is set to .minecraft. Next, click the Install button to finish installing Iris Shaders on your device. Once installed, follow these steps to use shaders in Minecraft 1.21.5 with the Iris mod:

1. Download a shader of your choice from popular mod repositories like CurseForge or Modrinth.
2. Open the instance of Minecraft with Iris Shaders installed.
3. Head to the Options menu on the loading screen.
4. Head to the Video settings tab. This will give you access to the main interface of Iris Shaders, along with an array of customization options.
5. Next, click on the tab marked Shader Packs in the right corner.
6. Click on the Open Shader Pack Folder button, which will open up the shaders directory.
7. Now, simply drag and drop your downloaded shaders into this folder.
8. Head back to the game. You will notice that the shader(s) you placed in the folder are now displayed in the list of available options.
9. Click on the shader you wish to use and hit the Apply button to apply and activate the changes.
10. Additionally, you can also check out the Shader Pack Settings Tab to modify the behavior of the parameters in the pack to suit your play style and needs. Most compatible shaders will let you modify features such as lighting, sky, water behavior, and more.

Once done, wait for a few seconds while the shader and the necessary assets get applied to your world. During this time, you might feel like the game is frozen or stuck — do not shut it down. Once done, go back to the loading screen and create a new world or load an existing one to enjoy the visual changes of the shaders in Minecraft 1.21.5.

8. You can also click on the Shader and then select Shader options to modify the settings of a pack to suit your needs. The settings in most shader packs will let you modify the behavior of features such as lighting, water, fog, and more.

Once done, click on "Done" to save your changes. Now, wait while the pack and its assets get applied to your world. After it is done, simply head back to the main menu to create a new world or join an existing one to enjoy the visual changes made with the shaders in Minecraft 1.21.5.
