Making a Minecraft Modpack (Client)

You can create a Minecraft modpack using the standard launcher by following this guide.
We always recommend using a launcher that is more suited to modded Minecraft such as the Twitch launcher but these steps will allow you to easily get a modpack ready to play with the standard launcher.

Tips & Troubleshooting

  • Lots of mods have variable options that can be edited by opening the configs folder in your modded profile folder.

  • To play with friends, they will need to have installed the same Forge version and mods in their own profiles.

  • Add only two or three mods at a time. This makes it easier to identify the causes of crashes when testing your modpack.

  • Common Reasons for crashes or mods not loading correctly:

    • Incompatibility with the version of Forge.
    • Incompatibility with the version of Minecraft.
    • Incompatibility with another installed mod.
    • Conflicts in item or block IDs.
    • Multiple versions of the same mod are installed.
    • Another mod is required for it to work.
    • It only works on a Minecraft server.
    • It needs to be activated with either a command or a configuration file change.
  • You can read the log and crash report files to help determine why your client is crashing.

    • Log files can be found in the logs folder and the most recent one is always named fml-client-latest.log.
    • Look for lines near the end of the log that have ERROR in them, clues to the cause will be on or near these lines.
    • The crash reports can be found in the crash-reports folder with a date and time of the crash in their filename.
    • Look for a line that has exception. The description of that exception could give you an idea of the problem.
    • In the Stack Trace and Caused by sections, look for lines that reference a mod that you have installed.
    • Both the log and the crash report may list all the installed mods and the state of loading that they reached. The state is usually indicated by some capitalized letters before the name of the mod. Look for mods that reached a different state than all the others for a potential cause of crashing.
  • If you are making major changes to your modpack then make a copy and use that for testing.

  1. Create a new profile in the Minecraft launcher.
  2. Name the profile differently so that you can tell which profile is for testing.
  3. Make sure you specify a new folder for its location.
  4. Copy the contents of the original profile’s folder to this new one.
  5. Continue to add mods and test your modpack.
  6. Once you have made all your changes, copy and paste this profile over the original.
