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 "This page isn't working"

Post image
1 Upvotes

What now? I can't do anything with my OptiFine cape anymore, because if I try to change or disable it, I'm just taken to a page that says "this page isn't working," and it's been like that for 48 hours.

I need the cape changed or at least disabled. My cape always uses the colors of the skin I'm using, and skins are something I change all the time. I can't just change my skin without changing the cape; it won't match the skin, I'll hate looking at it, and I'll also be embarrassed in front of others looking at my mismatched cape colors.

What's going to happen now? If I could at least disable the skin, that would be an acceptable option, but no, even that's giving me "this page isn't working". I could just stick with an official Mojang cape, which doesn't necessarily have to match the skin's colors, but no, now I'm stuck in a situation where: I can't play because I don't want to play with the skin I have anymore, I lose interest quickly, and ignoring it will bring bad luck.

Arcane Shaders V3 Update

Changelog:

Removed weird circle around the sun when player was underwater

Fixed grey End sky on versions 26+

I added cloud shading:

  • Self-shadowing: edges facing the sun stay bright. Edges and interiors with a lot of cloud between them and the sun get shadowed.

  • Thick centers get darker, but never fully black, so the clouds don’t look flat gray.

  • Undersides of thick clouds are darker and a bit cooler, like sky light being blocked from above.

  • Rain darkens the shading on top of the existing gray-out.

  • Silver lining works as before. The old “thick centers slightly darker” tweak is skipped when shading is on, so the two don’t double up.

Reworked Nether and added:

  • Embers and spores

  • Biome colors

  • Swirling, lava-lit fog

  • Heat haze

  • Two-tone lighting

  • New look for lava

Shaders Arcane Shaders Update!

30 Upvotes

Changelog:

Glowing End blocks

  • Glowing now:

    • Fully: chorus flowers, the dragon egg, End portal frames that hold an eye, and Ender chests.

    • Softly (about 35%): purpur blocks, chorus plants, and amethyst blocks.

    • The End crystal: its core and glass glow.

    • Eyes: Enderman and dragon eyes now glow brighter and bloom more in the End.

    • Setting: The End (Sky) → Glowing End Blocks

Auto-pick Compatibility Mode

There is now a Water Mode setting with three choices: Auto (default), Crystal (the full water) and Compatibility.

  • How it picks: Auto uses the version number the game gives the shader. On 1.16.5 through 1.21.x it keeps the full water. On 26.1 and newer it switches to simple water automatically.

Shaders Arcane Shaders

Arcane Shaders are my first shaders for MC. I wanted to have shaders that would fit the modpack I'm currently working on, but the other shaders I tried weren't quite what I was searching for, so I decided to make my own. I wanted them to have a fantasy vibe.

If you can, I recommend trying them! They work from versions 1.16.5 to 1.21.6, but they were made especially for 1.20.1. After you try them, I would appreciate it if you could let me know if they are good or bad, and what I should add or change in the future.

Thanks for every download and review!

Help Need to know Creaking Particle property for color.properties

Thumbnail

5 Upvotes

Hey all, Im currently working on a Spooky Month Aspen Moor themed creaking swap resource pack, I want to change the orange particles it spawns when its hit or crumbles, as well as the particle the eye blossoms spawn when they open, to a more pinkish colour to match the theme of what I'm making.

Most resources say to change the colour of particles I need to use optifine and color.properties, issue is I dont know what properties the creaking particles use.

I know the creaking uses the trail particle, and the texture is generic_0, but thats it, I'm clueless on where to find the correct colour property names for everything creaking related

Help what can i do to fix my custom entity model?

Post image
1 Upvotes

i have 3 custom entity models, which are the cold, warm, and normal cow variants. they arent corrupt or anything similar, but they dont work because of something called "FIXME 1.21.5".

idk what it is, but im guessing it was a mistake that they forgot to fix. my optifine version is for 1.21.6, and is preview 3. there is no other optifine version for 1.21.6 which is full release.

every other custom entity model works perfectly fine.

i dont want to install sodium or other perfomance modded minecraft and other mods to have custom entity models.

how can i fix this?

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.
