| Fabric doesn't come with a mod menu built-in. There's a mod called [[https://modrinth.com/mod/modmenu|Mod Menu]] that adds it.

| ==== I only have OptiFabric and OptiFine and Minecraft crashes on launch! ==== | ==== I only have OptiFabric and OptiFine and Minecraft crashes on launch! ==== |
| This is because OptiFabric is currently incompatible with Fabric Loader 0.15.0 and above. This is why you'll see ''java.lang.NoClassDefFoundError: net/fabricmc/tinyremapper/IMappingProvider'' in your log. You'll need to use Fabric Loader 0.14.25. | This is because OptiFabric 1.13.25 and below are incompatible with Fabric Loader 0.15.0 and above.

| | ==== OptiFabric crashes on my 1.18.2 or 1.19.2 instance when I add Fabric API to it ==== |

| Fabric's rendering patches, while as minimally invasive as possible, make some assumptions about the data format used internally by the vanilla rendering system. Shaders break this assumption, so things go awry. Workarounds do exist and are implemented by the most recent versions of said unofficial mods. | Fabric's rendering patches, while as minimally invasive as possible, make some assumptions about the data format used internally by the vanilla rendering system.

| ==== My instance with Sodium and Continuity crashes when gravel/sand falls or when a piston extends ==== | ==== My instance with Sodium and Continuity crashes when gravel/sand falls or when a piston extends ==== |
| This is because Sodium does not yet support the Fabric Rendering API which some mods such as Continuity use. This is why you'll see ''java.lang.NullPointerException: Cannot invoke "net.fabricmc.fabric.api.renderer.v1.Renderer.meshBuilder()" because the return value of "net.fabricmc.fabric.api.renderer.v1.RendererAccess.getRenderer()" is null'' in your log. Add the [[https://modrinth.com/mod/indium|Indium]] mod to resolve this. | This is because Sodium 0.5.x and earlier do not support the Fabric Rendering API, which is used by many mods, including Continuity.

Add the [[https://modrinth.com/mod/indium|Indium]] mod to resolve this. |
| | |
| | ==== Text has been replaced by squares/tofus in my instance with Sodium ==== |
| | This is usually because you have Sodium 0.5.x and below and do not have Indium, or because your versions of Iris and Sodium do not match. |
| | |
| | ==== My mods aren't being loaded! ==== |
| |
| ==== Can Fabric run together with Sponge? ==== | * Make sure you do not use the Essential Installer or Iris Installer. You can get those mods from Modrinth and CurseForge and put them in your mods folder like any other mod. Use the [[https://fabricmc.net/use/installer/|Fabric Installer]] to get Fabric Loader. |
| | * Make sure your mods are located in the "mods" folder in your game directory. The default mods folder on Minecraft Launcher for Windows is "%appdata%\.minecraft\mods". |
| | * Make sure you have the Fabric versions of mods. |
| | * Check your log or Mod Menu to see which mods are loaded. |
| | * Check that Fabric is loaded by checking the bottom left corner of the title screen, or your log. |
| | * If it's vanilla, re-run the Fabric Installer. Make sure you're launching the Fabric installation and that the version of the installation is Fabric Loader. |
| |
| Not at the moment. Sponge does not yet have a ready API or a working implementation for 1.14, the Minecraft version that Fabric runs on. | |
