Installation Guide

A step by step guide on how to successfully install using either Iris or Optifine.

Installation with Optifine

Please follow the steps below for a successful installation.

Never allocate more than half of your system’s ram, and no more than 6gb max. Only allocate more ram if your ram usage is more then 75% (You can check your RAM usage in-game by pressing F3 on your keyboard).

Prerequisites

Java

Go to https://www.java.com/en/download and click the “Download Java” button to download, then open the downloaded installer and follow the installer instructions to install.

Mod

Optifine

Go to https://optifine.net/downloads and download optifine for your desired version by clicking on “Download” button, after waiting for a few seconds click skip on top right corner which will lead you to the final real download page and click on the "Download" button once again.

After downloading double click on the downloaded optifine.jar file and click "Install", Click on the "OK" button on the successful installation popup to close the installer.

If you can't see the latest Optifine version which you may desire, click on the "Preview versions" button on the website which will reveal early builds that you can download.

Resource Pack

Installing resource pack

Assuming you already have downloaded the texture pack, move the downloaded resourcepack.zip files to the resourcepack folder in your .minecraft directory, then in-game go to Options > Resource Pack, select the resource pack(s) on the left side.

A texture pack might have additional addons, the addons must be loaded at the top of the “Basic” pack in any order.

Shaders

Choosing the right shader

For any of my texture packs it is recommended to use a fully LabPBR compliant shader, here’s a list of LabPBR shaders to choose from https://wiki.shaderlabs.org/wiki/LabPBR_Supported_Packs

After downloading the desired shader paste the shader.zip file in your shaderpacks directory.Now in-game go to Options > Shaders and select the downloaded shader.

Configuring Shaders

Shader settings

In order to achieve screenshot like results we need to change some settings and enable the resourcepack features, to find the recommended settings for your desired shader please move to the shader settings page.
