- Step 1: Open the modpack settings
- Select the modpack in Prism
- Click on “Edit”
- Click on the section on the left that says “CurseForge” (or “Modrinth”)
- Step 2: Update the modpack
- Click on “Update pack”
The button is located near the right of screen next to the “Update to version” dropdown
- Step 3: Download missing mods
(you should only have to follow this if you downloaded from CurseForge)
- In the dialog that pops up, click on “Open Missing”
A bunch of CurseForge tabs will open, download every mod that opens
- Once you’ve downloaded all the mods, go back to the dialog and make sure it says “All mods found” in the bottom left.
- If it says all mods found, click on “OK”
- If it doesn’t say all mods found, scroll through the list and make sure you have every mod downloaded.
