How to Use Shaders and Optifine in Minecraft 1.8!





Introduction: How to Use Shaders and Optifine in Minecraft 1.8!

About: My brain is a Raspberry Pi and I eat only micro ATX motherboards, occasionally munching on open-source software like Blender as a snack.

OUTDATED: This instructable no longer can apply as the clients I used aren't available anymore

Regardless, the information here might be useful to some people, salvage what you can from it.

Here is the issue:

You love the look of Shaders in Minecraft, but the GLSL Shaders mod is not by any means the most efficient in video rendering. You get a fantastic FPS boost with Optifine, and you tried to run the GLSL Shaders mod with it in Forge, but you run into an error - Texture mapping is glitched, and in some cases text doesn't show up as their proper characters, rather white boxes...

I found the solution to this after lots of research and figiting around with Minecraft.

Move along to find out how!

Step 1: Install Forge

This probably sounds obvious but go ahead and do it. Follow the link and download the 1.8 release.

Minecraft Forge

Once you do so, check to see if you have a Forge profile in Minecraft.

If you can't find a Forge profile, click the New Profile in the bottom left corner and create a profile named Forge. Then, select Forge 1.8 from the Release tab. Hit save to create the profile.

Once you have the profile, run it once to make sure it works.

Step 2: Install Optifine

NOTE: There is a specific release you MUST use, if not you will run into errors or potential client crashes.

Go to Optifine and download the OptiFine_1.8.0_HD_U_D5. Make sure you don't download a different jar file, otherwise you will run into errors.

Careful here, please read.

The Optifine website and mod creators are funded by Ad Fly, which does mean you will have to sit through an ad. Keep in mind these ads are not "secure", so do not click the ad, go to the top right corner and wait until it says "Skip Ad".

Next you will be brought to a page with the download link. Click it and Optifine will download, but another ad will open in a new tab. Exit out of the ad.

Now that Optifine is downloaded, you need to run the Jar file. Run it and it should install a profile (just like Forge did).

If you don't find the Profile, create one the with the same process as you did with Forge. Then run it once and make sure it works.

Step 3: Install the Shaders

For this you will install a variant of the GLSL Shaders Mod (you will run into another Ad Fly page, click Skip Ad in the top right corner), install this mod and run it once (you might need to create a new Profile again). If it works, good job.

While you are here, install these Shaders (I like these best for performance/visual results, download the medium+ shaders if you want shadows) and put them into the shaderpacks folder. The shaderpacks folder is located at C:\Users\*****\AppData\Roaming\.minecraft\shaderpacks for Windows users.

The easiest way to get to \Appdata\Roaming is by typing %appdata% into your navigation bar.

Also, a large shader pack is available online containing several dozen shaders of different visual styles. Do a Google search to find a recent pack (as new shaders are constantly being developed).

Step 4: Do Some Tweaking

In order to get Optifine and Shaders to work in Forge, you need to launch OptiFine and tweak some settings.

4 things need to be disabled.

1. Anti-Aliasing OFF
2. Anistropic Filtering OFF
3. Fast Render OFF
4. Natural Textures OFF

Once those are all disabled, you may move on to the next step.

Step 5: Put Optifine and Shaders Into the Mod Folder

Navigate back to .minecraft (same place as the shaderpacks) and look for a folder titled mods, if it doesn't exist create it in .minecraft. In this folder, place the OptiFine_1.8.0_HD_U_D5.jar (the files you downloaded) inside. Then, run Forge to see if it works. Launch a single player or server world and see if Optifine works. Once that works, you then need to place the ShadersMod-v2.4.11mc1.8.jar into the Mods folder (make sure Minecraft is closed).

After this is done, you should be able to run both Optifine and Shaders together. If not go back over the steps and try troubleshooting it.

Step 6: Optifine and Shaders in Action!

    This is very outdated. You can download optifine and it had integrated shader support now

    Sorry for responding so late, I'm not active here

    On step 3, there is no link for me.

    Can you post the link here please?

    I don't know what else to provide, the clients I used aren't anywhere I can find. Just salvage what you can from the tutorial then do some research to see if you can get compatible clients.

    Sorry about that

    When I click one of the shader option the game exists itself and brings up the minecraft launcher. And there is a message saying (in the output thing) shader pack default. wat to do?

    Can you send a screenshot via Gyazo or something?

    Also, I'd need to know what your client is. Is this the GLSL Shader Client or Optinfine+Shaders in Forge?

    I don't understand what u meant by client. If u mean launcher then TeamExtreame Minecarft Launcher 3.5.1.[/IMG]

    Hope this Helps. (Sorry for the late reply I didn't think that u would reply this fast)

    No I have the Optifine + Shaders In forge. I think I have the official client.

    The client is the actual game itself, BTW.

    What's going on is that you most likely have an incompatible forge/mod setup, try using a different forge client, I don't know what else to do since I can't actually play your game myself.

    I have Optifine HD 1.8. I have team extreme minecraft launcher. And i don't have GLSL Shader Client caz it crashed my game caz i already had optifine. I think i have the normal client. I didnt change it or anything. (Sorry for the late reply I didn't think that u would be nice enough to reply that fast)


    How do you disable the settings on optifine? How do you even launch optifine?

    Follow the instructions to set optifine as a profile, from there you can go into your Minecraft settings in game and it'll be under Video settings. Navigate around the new video options.

    I've got a problem, I went to the link to download the Optifine jar file and the specific one in this tutorial isn't there anymore. What should I do?

    Cool! will definitely try this, what kind of FPS do you get, and what FPS do you get before instalation for comparison?

    Before with just Optifine and 8 other client mods I got 300+ fps (I am using an AMD Radeon 360 R7 graphics card, it's a decently powerful card), with most shaders I'll getr 30 fps, but with Chocapic's medium shaders I get 60 fps on average. A lot of shaders run nicely, but things like SEUS are inefficient with rendering, so they get as low as 20 fps in highly detailed areas.

    One shader is a cartoon shader, Naegeos Cel Shader (or something like that), it is really simple and makes everything look like a comic book, it can get 100+ fps at times.

    Hope that helped! - Sam

    thanks, though from what your saying, I'm not sure if it will work for me. I get 50-60 FPS usually without any mods, so I'm not sure if shaders will be functional for me. I'll just have to try and find out

    I also recommend you overclock your graphics card if you have enough thermal dissapation. I turn my fans to 60 percent and set a 10% clock speed increase (also allotting more power) and set the memory bus to 1800mHz.

    what do you do if you have a black screen do i need to upgrade my graphics card

    You may need to get a better graphics card, but before you drop a few hundred go back and check if you missed any steps. Also I've had issue with 75hz on my monitor, set the pixel clock to below 165000khz.
