About this Mod

About

HexConnect is an addon for Hex Casting that applies a number of fixes which enable some Fabric-only Hex Casting addons to actually load on Forge when using Sinytra Connector.

Please note that currently this mod is just focused on getting Fabric addons past the loading stage on Forge, and that I cannot guarantee 100% functionality or stability for every addon. For this reason, please be very diligent when reporting any bugs to mod authors by making sure you verify that the issue occurs in a barebones instance without HexConnect installed, as HexConnect may potentially cause issues.

Usage

To start using HexConnect, ensure that Sinytra Connector, Connector Extras, the Forge version of Hex Casting, Cardinal Components API, and all their dependencies are installed.

From there, depending on the addons you are wanting to use, you also may need to install the Forge version of Architectury API and Fabric Language Kotlin (and yes, that means you would have both Fabric Language Kotlin AND Kotlin for Forge because of Hex Casting's dependencies).

Some addons also depend on MoreIotas, and possibly also Hexal (which in it self depends on Geckolib). You can get MoreIotas under its Github page's releases tab here. The working Hexal build can be downloaded here (same link as the one pinned in the Hex Casting Discord). Geckolib can be found on Modrinth. Make sure that they are all their respective Forge versions.

Lastly, refer to the section below for what Fabric addons you can install.

Support

Below is a list of the Fabric Hex Casting addons that I have tested and confirmed that I could load on Forge when following the steps described above. I have linked the Modrinth page along with the version which I tested for each addon that is available on Modrinth. Additionally, the Hexxy4 modpack has some addons (or newer versions of some addons) which are not currently available on Modrinth, but can be downloaded off of the Hexxy4 Github page. For these addons I've also included a link to their respective files as of commit 3df1c1a, as I have also tested and confirmed that the versions available as of commit 3df1c1a also load on Forge.

As addons are updated, changes made might break their support for being loaded on Forge, however you can always experiment with newer versions as you wish and see if they still work. This list also might not cover every addon that works with HexConnect, so again, feel free to test addons not on this list.

Credits

HexConnect is made possible by everyone who has helped develop and bring to life both Hex Casting and Sinytra Connector. HexConnect also is nothing without all the addons which the community has created, so credit to all the addon devs as well.

Part of Hex Casting's Fabric side api is packaged in with HexConnect to ideally make things work, and all that code is provided under the MIT license.

Additionally a modified (and version bumped for priority) version of serialization-hooks for 1.20.1 is also embedded, again provided under the MIT license.

Frequently Asked Questions

HexConnect server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is HexConnect compatible with forge?

HexConnect officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HexConnect – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HexConnect consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
