This thread is for keeping track of compatibility problems caused by Fabric mods that don’t currently support Quilt. If you’ve found an incompatible mod (or a mod listed here that is now compatible), please post below with information about it.
When listing an incompatibility, please ensure you’ve reported it to the developer and provide a link to your report! Simply listing mods here does not help get them fixed.
Unreported
The following mods are incompatible, and nobody has properly reported this incompatibility (for one reason or another). If possible, please consider generating a usable log, reporting the issue via the project’s official channels, then returning here with a link to your report.
Limitless (GitHub)
Limitless is marked incompatible because it relies on a mixin plugin that fails to load on Quilt, with ExceptionInInitializerError:null
. Additionally, while the Modrinth implies that the project is being updated and the GitHub is still receiving commits, the repository has been archived on GitHub. This makes it difficult to know where or how to report the problem.
Seamless Loading Screen (GitHub)
Seamless Loading Screen is marked incompatible because of an unusual exception thrown when saving and quitting. This is a non-fatal error, but may be causing issues that are invisible to the user.
java.nio.file.FileSystemException: : Is a directory
Reported
The following mods have had reports created regarding their compatibility, but we haven’t heard back from them yet.
OpenMCSkins (GitHub)
OpenMCSkins is marked as incompatible because it relies on Fabric Loader Internals, which Quilt does not support. The relevent GitHub issue can be found here.
Pending Support
BCLib (GitHub)
BCLib (which Better Nether and Better End require) is marked incompatible because it relies on multiple unstable implementation classes/methods in Fabric API. Some efforts have been made to solve this problem, but no public API exists in Fabric API that gives them access to EndBiomeData
, so a fix may take some time.
For more information, please read the relevant issue on GitHub.
Better Loading Screen (GitHub)
Better Loading Screen is marked incompatible because it gets stuck in an exception loop, repeatedly logging the following message ad infinitum:
java.nio.file.NoSuchFileException: /assets/minecraft/textures/gui/title/mojangstudios.png
For more information, please read the relevant issue on GitHub. However, please note that the developer is not accepting reports regarding non-Fabric loaders, and is too busy to work on this problem for now.
Camera Overhaul (GitHub)
Camera Overhaul is marked incompatible because net.fabricmc.loader.util.version.SemanticVersionImpl
appears to be missing from Quilt Loader.
For more information, please read the relevant issue on GitHub. This issue has been marked as a bug
, so we’re assuming that support is planned.
Immersive Portals(GitHub)
Immersive Portals is marked incompatible because of the following non-fatal errors:
Unknown custom packed identifier: imm_ptl:spawn_entity
missing entity for data tracking ClientWorld minecraft:overworld405
These errors don’t crash the game, but do prevent Immersive Portals from functioning as intended.
As shown in this post, Immersive Portals has fixed this problem. However, a release with these fixes hasn’t been published yet.
MultiConnect (GitHub)
MultiConnect is marked incompatible due to a bug in QSL and QFAPI. Compatiblity is pending a fix on Quilt’s end.
For more information, please read the relevant issue on GitHub.
Non-fatal errors
The following mods have errors on Quilt Loader, but are still reasonably able to function normally. Any mods listed here will be posted with an explanation of what’s broken.
Essential (Website)
Essential is marked incompatible because net.fabricmc.loader.metadata.ModMetadataParser
appears to be missing from Quilt Loader. However, this is a non-fatal error which only prevents it from being added to Mod Menu - it should still work normally.
No support planned
The following mods have confirmed that they have no intention of supporting Quilt. This may be for many reasons — please do not harass developers that do not wish to support quilt.
LibJF (GitLab)
LibFJ is marked incompatible because it relies on unstable implementation methods in Fabric Loader, specifically getInfo
in net.fabricmc.loader.impl.ModContainerImpl
. If possible, the mod should be encouraged to find a stable Fabric API call that does what they need.
Support for Quilt in LibJF is not planned. This GitLab issue states that Quilt is unsupported and that things were explained in a discussion on a Matrix channel. Here’s a screenshot of that discussion.
This issue on the Quilt Loader GitHub states that it’s likely to be impossible for Quilt to add support for what LibJF is doing.
