  1. Quick Question: So I like playing on public non-modded servers (hypixel, mineplex, etc.) and if I have this modpack (or any modpack) downloaded, will I still be able to play those public non-modded servers? If not then is there a simple solution to it?

  2. The new updated Hexxit kind of sucks because many of the mods from the original aren’t implemented into the new one. For example, the chocolate quest mod and the backpacks mod

  3. Hey, Drayux I can’t download Minecraft from twitch. It just keeps on reloading the page when I click “download”

  4. So the Twitch Launcher is Seperate from the main Launcher? If I wanted to play Hexxit I would have to use the Twitch Launcher right?

  5. if u having this problem called ''Failed to download file, the file contents differ from what was expected. Name: jna-4.4.0.jar''
    Try this:

    Manualy download this file:

    Then put it here: C:UsersgarnetwitchminecraftInstalllibrariesnetjavadevjnajna4.4.0jna-4.4.0.jar

  6. hey man. dont know if youre still replying to comments but, whenever i attempt to open the modpack in the launcher it says, "Failed to download file, the file contents differ from what was expected." this happens with every modpack ive attempted to open. any idea whats going on?

  7. I know this is german, but essentially it is telling me that it couldnt download a file since it wasnt the same?
    It literally has the same name. Its the same problem as in the video where you said just restart your launcher. It made no difference.

    Existiert: File

  8. I don't know if having winrar affects it, but whenever I download it it'll give me the files instead of the actual thing to import it inside the twitch launcher. I also tried putting the winrar file of the hexxit pack without extracting it, but the game keeps crashing. Is there any way you can help?

  9. Great tutorial, took a bit of tinkering but got it to run at least. Is there any mods i should disable off the bat? I have somewhat frequent crashes and was wondering what mods to disable since mc launcher wont open my crash report. Also are there texture packs that work with this pack bc i would love to have faithful or something for the default mc assets? Any help would be greatly appreciated

  10. I have the twitch desktop app downloaded, but when I go into settings for Minecraft on the twitch launcher I don't see an option to allow mod management. My twitch desktop app also looks different from yours, could I be using an incorrect version?

  11. I have two forge things will this still work it doesn’t say 12 anything on the create custom profile it only say 14 forge things

  12. When my friend opens minecraft from twitch its the normal launcher and in the middle it says "play demo" and idk how to help him.

  13. Why do you only have 237 Subscribers? That video was informative, well edited and you are not a squeaker 😀
    Thanks a lot for the vid m8

  14. YES! Thank you so much I'm actually so happy right now
    I've always wanted to play Hexxit for a while now but couldn't find any tutorials until I came across yours!
    This also worked much quicker than expected!
    Y e s.

  15. Hexxit thinks my resulotion is somehow 4K so if I maximize it starts lagging and if I hit fullscreen it just takes op 1/4th of my screen in the corner with the correct resolution (1920×1080). Does anyone know what's happening?

  16. Invalid maximum heap size: -Xmx4096m

    The specified size exceeds the maximum representable size.
    My pc uses 16 gb of ram
