Compatibility

Applies to Motorcade 0.0.0-beta.1 for Minecraft 1.21.1 (NeoForge).

Loaders

Loader	Supported
NeoForge 21.1.249+	Yes
Fabric	No — this port is NeoForge only
Forge	No

Requirements

Minecraft	1.21.1
NeoForge	21.1.249 or newer
Java	21
Vellumli 1.0.0+	Required, on both client and server

Nothing else is needed. No other library, no optional integration.

Client and server

Both are required. Motorcade registers its network channel as not optional, so a client without the mod is refused at connection time. That applies to a dedicated server too.

Multiplayer, and the one thing to be careful about

Vehicles work in multiplayer, and other players see yours moving. But driving is client-authoritative: your client simulates the movement and sends its physics state to the server four times a second, and the server accepts it without checking it.

A modified client can therefore drive as fast as it likes, boost without limit, and fly. If you run a public server you need anti-cheat. This comes from the original mod's design and is not something the port introduced.

The server does authoritatively handle building a vehicle, fitting and removing attachments, and the crowbar.

Dedicated servers

Should work. World changes happen on the server, client-only rendering code is properly split out, and the only command the mod adds is client-side.

Other mods

Mod	Support
JEI, EMI, REI, Jade	None at all. There is no integration. Motorcade's own recipe type has no external viewer, so there is no in-game recipe lookup for vehicle parts. The guide book is the substitute.
Controlify	Documented in the guide and in the translation keys, but not implemented in this build.
MidnightControls	Nothing. Some leftover translation keys only.
Mods in motorcade:dash_panel_boostables	Soft support: driving over an unpowered Dash Panel boosts and shoves them.

Known limitations

Functional gaps in this build:

• No fuel system. A vehicle never runs out and can be parked forever.
• No config file. Balance is fixed in the mod's data. Pack authors change it with data packs, not settings.
• No recipe-viewer integration, as above.
• Controller support is inert, as above.
• The Automobile Pressure Plate and the Allow block have no recipe. The Allow block is not even in a creative tab.
• The c_arr frame and the Creative engine have no recipe either — prefabs and creative only.
• Bikes and wheelies cannot be built. The code supports a two-wheel vehicle, but every frame in the game has four wheel positions. Only a data-pack frame with two wheels would enable it.
