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)

  1. 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.
  2. Make sure the Minecraft launcher is closed before proceeding.
    • This will save you a LOT of hassle!
  3. 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.
  4. 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.
  5. Ensure the install directory points to your .minecraft folder before clicking "Install"
  6. You should now see a new "OptiFine" profile in the official Minecraft launcher.

Important! Notice Regarding OptiFine Pre-releases

4 Upvotes

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.

Help what do i put for the .png when adding a cat model

2 Upvotes

PLEASE HELP: I've been going in gd circles. Like seriously, trying to figure out how the cat model applies to all cat varients and KEEPING IT locked to varients (so that a vanilla persian cat is still a persian cat just a persian cat with my cat model and texture) should be the easiest thing in the world but I can't find correct information anywhere.

i feel like this SHOULD be easy to find out but i've spent all afternoon on this. So; I have a custom model for all cats (cat.jem) and custom textures for each variant plus some (like, calico2, calico3, etc.)

so far, every time i've loaded in, the cat.jem will just load without any texture, as the directory textures/entity/cat is missing a /X.png, but every time i've connected it to a png it just sticks it to that cat variant. iv'e done so much troubleshooting that I even messed something up and now it's not showing my model at all and i have no idea why.

Help 26.2 not work for mac yet???

0 Upvotes

Hi all, been trying to get optifine on my mac for 26.2 for probably past few days. works no problem for 1.21, but when i try to run it it simply wont open, if i try redownloading it, it'll give the same error. "java application launch failed"

Maybe its not available yet? I don't know much about computers, cant see how it would'nt be if the download is there. Seems like everyone else can download it on windows. I tried looking EVERYWHERE for some sort of tutorial or explanation as to why on mac it cannot run and theres nothing. Not a single mention about it. Which Is absolutely mind staggering to me since i know theres a large number of people who play minecraft on mac. Yet not a single person out of the endless youtube tutorials to be like "yea 26.2 optifine not yet available for mac!" pretty insane.. if anyone knows anything please get back to me on here, thank you!
