About this Mod
CC-Holo
CC-Holo is a ComputerCraft/CC: Tweaked peripheral provider for Minecraft 1.20.1 (Forge) based on the
Plethora-Fabric and
Plethora mods aimed at server admins and mapmakers. It provides a holographic
display peripheral that server admins (anybody with creative mode, and permissions to place command blocks) can use to
display 2D and 3D objects on player's screens. It also allows for basic key capture during gameplay, and more detailed
mouse and keyboard capture through a 'capture mode' GUI.
Requirements
- Minecraft 1.20.1
- Minecraft Forge 47.4.9
- CC: Tweaked 1.113.1–1.116.1

intended to be a port of, or replacement for Plethora, but a Forge port of Plethora may happen separately in the future.
Bug reports, feature requests, and pull requests are welcome, but maintenance of the mod will primarily suit the needs
of the commission.

CC-Holo 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 CC-Holo compatible with forge?
CC-Holo officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with CC-Holo – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CC-Holo 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.
