Modpack won't load with Optifine

[Caravaneer546]

I can get the modpack to load without Optifine, but once I install Optifine on to the pack, it won't load. The launcher closes as if it's loading Minecraft, but it just comes back. I can't get on the Minecraft menu at all, just the Technic Launcher. And yes, I am installing Optifine correctly.

Follow these instructions:

You will get the odd visual anomaly, but it does work.

Blacktooth has a good way but I still wouldn't recommend getting optifine for this modpack as it may glitch out, add intense amounts of lag spikes, or you game may even crash.

I just want to chime in here as I have gotten this mod pack to work with both OptiFine as well as Shaders however I personally experienced some heavy lag spikes every once and a while as well as some odd glitching (It was dependent on what shaders I was using).

 

Basic thing you need to know in my experience was that any OptiFine version for 1.6.4 above C6 will not load properly. Again strictly speaking from my experience with it.

Um dont listen to halestoemXV

 

TOTALLY listen to Blacktooth!

 

it worked omg it worked! tekkit 1.6.4 with optifine! i havent been able to play in over a month due to updated ect, the link is good, it is trusted and does infact work!

 

 

optifine is loaded and working in my 1.6.4 FROM MODS FOLDER!! no opening and splicing or deleting meta-inf or anything! like omg its lovely.

 

optifinefml.7z download link (dropbox)

How to use
1. Make a copy of OptiFine_.jar file and rename to "[0000]_OptiFine_whatever yourssays.jar" (or other meaningful name) .
2. Open optifinefml.7z and [0000]_OptiFine_.jar in archive program (7-Zip or WinRAR or WinZip).(for 7zip, open 7zip then navigate to it, has issues opening directly if winrar takes over)
3. Copy files and folders inside optifinefml.7z to [0000]_OptiFine_.jar .
4. Close archive program.
5. Copy [0000]_OptiFine_whateveruput.jar to mods folder.
6. Make sure the original OptiFine_.jar is not also in mods folder.
 

ONLY WORKS with Optifine HD c4 or c5!!!

http://optifined.net/adloadx.php?f=OptiFine_1.6.4_HD_U_C5.jar

 

I used the above exactly and my tekkitmain 1.6.4 now loads perfectly fine with optifine!

[ btw i used c5 ]

For future searchers of fixes: Simply download the correct version of Optifine (OptiFine_1.6.4_HD_U_D1.jar) for 1.6.4 and drop it in your mods folder.

I've tried adding OptiFine_1.6.4_HD_U_D1 to my mods folder for Tekkit and it hasn't worked. Any suggestions?

 

FIXED - I downloaded it from the Optifine website rather than from the Minecraft forum link.
