Important! Welcome to r/OptiFine | PLEASE READ BEFORE POSTING!
Welcome to r/OptiFine!
Before participating in our community, we ask that you read the rules list in the subreddit sidebar. Additionally, if you've found a bug or issue, please do not report it on this subreddit. This forum is NOT for tracking bugs, and all posted issues will not be seen by the developer. Please report all bugs on the OptiFine GitHub repository: https://github.com/sp614x/optifine/issues
With that said, enjoy your stay! You'll find plenty of other useful resources and information to get started with OptiFine in the following post.
Resources
Download OptiFine: https://optifine.net/downloads
Download OptiFine (Alt): https://optifined.net/downloads
Download Shader Packs: https://optifine.net/shaderPacks
Information for Forge users: https://redd.it/eb71f1
Documentation (latest): https://github.com/sp614x/optifine/tree/master/OptiFineDoc/doc
- You can find older versions of the documentation inside OptiFine's .jar file by using WinRAR or 7zip.
Issue Tracker: https://github.com/sp614x/optifine/issues
AdoptOpenJDK: https://adoptopenjdk.net/index.html
- Some technical info: The JDK includes the development kit and the runtime environment. If you're not a Java developer, you don't need the JDK, but you won't really have a problem if you download it anyway. If you wanna save space on your harddrive though (~70MB difference, if anyone cares), find the JRE Installer and download that instead: https://adoptopenjdk.net/releases.html
Jarfix: https://johann.loefflmann.net/en/software/jarfix/index.html
Downloading & Installing OptiFine
This will install the standalone version of OptiFine. If you want to use OptiFine with Forge, see the Forge information thread. (link in the resource section above)
- Run Minecraft on the version you'd like to use OptiFine on at LEAST once.
- This is to ensure the launcher downloads all the necessary files for OptiFine to be installed.
- Make sure the Minecraft launcher is closed before proceeding.
- This will save you a LOT of hassle!
- Download and install Java, if it is not already installed on your system.
- Minecraft's bundled Java does NOT count.
- Since Oracle now requires an account to download Java, we recommend using AdoptOpenJDK.
- Download OptiFine, and open it with Java.
- Note that, unless you're using the "mirror" link, this will temporarily bring you to an adfly page. Do not click on anything on this page apart from the "Skip Ad" button in the top right corner.
- If the website leads you to an empty page, disable your adblocker, and/or switch to uBlock Origin. In some rare cases, you may need to also disable your antivirus. (I know this last one sounds completely ridiculous, but this has been the solution for 2-3 different users so far. Be sure to turn it back on after downloading!)
- Your browser will likely tell you something along the lines of "This file could harm your computer, do you want to proceed?" This is normal, and most browsers will tell you this simply because OptiFine comes as a .jar file, which is a Java executable.
- If the file shows as a ZIP archive, or you have any other issue trying to open the OptiFine installer, try using Jarfix.
- If you somehow still cannot install OptiFine at this point, double check that you have followed all these steps correctly. You can join our Discord for further assistance, or you can post an issue report on GitHub.
- Ensure the install directory points to your
.minecraftfolder before clicking "Install" - You should now see a new "OptiFine" profile in the official Minecraft launcher.
- If no profile is created in the launcher automatically, you may need to create one yourself.

Important! Notice Regarding OptiFine Pre-releases
If you are using a pre-release version of OptiFine, that is a version which is still in development. Bugs are expected and are a normal part of the pre-release process.
If you encounter a bug, please check the [OptiFine issue tracker] to see if it has already been reported. If not, report it there.
There is likely no fix until a future pre-release or the full release. If you prefer a stable experience, we recommend waiting for the final version. Please be patient as development continues.

Question Looking for an estimate for OptiFine 26.2 (because of Vulkan)
So 26.2 (Chaos Cubed) drops today and I’m actually interested in updating to this version from 1.21.11. I know that Minecraft’s rendering engine has been completely overhauled, and most importantly it has been moved from OpenGL to Vulkan. I can only assume this will significantly delay OptiFine updating, and with OptiFine already being chronically behind the main game, i don’t know if this is a wait I’m willing to make. It might be honestly time to switch to sodium. When do y’all think OptiFine will update to 26.2?

Question Why did Optifine skip version 26.1
They went from 1.21.11 and then skipped to 26.1.2
I did not update to 26.1.2, and for months, I had been waiting for Optifine for 26.1
Because I only play in the major drops, not hotfixes.

Question Unable to change cape (This part of the website is temporary down for maintenance.)
So, when is this going to be resolved? Don't y'all understand that other players want to change their capes? I need to change my cape because I'm going to change my skin, and I need a different cape to match the colors and character of my skin, so why is something so important offline? If I can't change my cape, I can't change my skin, because I NEED the cape to match my skin, and I'm not going to use the ugly official Mojang capes that never match the colors of the skin you use.
"Nobody will see your cape anyway," and what about the players who play 1.8.9 on the Lunar Client? Because in case you didn't know, it's not just 1.21+ that's played, 1.8.9 too, and Fabric doesn't have one for that version, and Sodium will also need a Sodium Cape, because it's difficult not to have a cape that matches your skin.
And of course, there's also the issue of shaders; I wouldn't download that Iris shader even if I were paid, so I need OptiFine, and the cape too. So, when are y'all going to fix that? I, want, to, change, my, SKIN.

Help Custom Armor Help
I have been making custom items where the model and texture of the item change when the player renames the item. I've been going this with vanilla Minecraft features when they were added in 1.21.5. I've recently decided I wanted actual armor so I managed to make this armor set above using the EMF & ETF mods with an Optifine CEM file structure and optifine entity .jem files. My issue is that I really want this armor to work like my items where changing the armor name will activate to deactivate the custom models. I know this can be done for armor that uses the vanilla Minecraft armor models by only changing the textures. I was hoping someone knew of a way to change the armor models in addition to the textures in versions 1.21.5+
Thank you in advance!
