I use these mods whenever I play mini-games in 1.8.9
I record videos, so some of these mods are helpful for recording (Replay Mod, Fullbright, Ungrab Mouse Mod)
Here is my channel if you want to check out some of my recordings using these mods.
I don't normally use the Replay Mod when playing Hypixel, because I have mainly been uploading uncut games, and also, Hypixel already records all the games for me.
All the mods are compatible with 1.8.9 Forge
You do not need twitch to use this modpack. You only need 1.8.9 Forge. It is simply a .zip file with all the mods in it. You just extract the file in your mods folder, and you are set.
Make sure you read the README.txt file for more instructions on how to use it.
Here are all the mods that are in the modpack:
Fullbright - https://www.curseforge.com/minecraft/mc-mods/fullbright/files/2579022
Gives you night vision
Auto Sprint Mod - https://www.curseforge.com/minecraft/mc-mods/auto-sprint-mod/files/2650901
Toggle sprint like in more recent Minecraft versions
Replay Mod - https://www.replaymod.com/download/
Records everything around you so that you can view the recording in spectator mode later. This can take up a lot of your storage space if you record everything.
Ungrab Mouse Mod - https://www.curseforge.com/minecraft/mc-mods/ungrab-mouse-mod/files/2520628
You can move your mouse off your screen whenever you want without having to open chat or block the screen. Great for recording!
THIS IS NOT IN THE MODPACK(due to licensing), BUT I SUGGEST YOU USE THIS TOO
Optifine - https://optifine.net/adloadx?f=OptiFine_1.8.9_HD_U_L5.jar&x=f0ee
It helps with the graphics side of Minecraft
I also use the 5zig mod. I am not incorporating this in the modpack because I'm not sure if you want it(and licensing). I only use it to display my CPS while I'm playing. It has a lot of extra features that I keep disabled, and that you might find annoying, but if you are a making videos, or you like to see that kind of stuff, you might want to use it: https://5zigreborn.eu/downloads/
