- There're 3 server-side alias

,/vvfabric
and/viaver
, and a client-side command/viafabricclient
for Minecraft 1.14+ (OP permission level 3 is required for these commands, received by Entity Status Packet)
- ViaVersion configuration is available at
.minecraft/config/viafabric/viaversion.yml
- ViaFabric configuration is at
.minecraft/config/viafabric/viafabric.yml
- You can disable it in the menu or by setting global protocol version to -1 (this will keep per-server translations still enabled)
- For using globally, set the protocol to AUTO or -2. For using in a specific
server:
ddns.example.com._v-2.viafabric
- The protocol detector will try to ping with the client native protocol version, differently than multiconnect which uses -1 version, which may detect the native server version.
- Append ._v(VERSION).viafabric.
- Examples:
minigame.example.com._v1_8.viafabric
,native.example.com._v-1.viafabric
,auto.example.com._v-2.viafabric
- No, ViaFabric cannot be used with ViaFabricPlus.
