Rubik Saer 2: Tutorials and Common Issues.

The SAER2 server is made possible through a collaboration between HolyHosting and Rubik. This guide provides a collection of tutorials, important information, and solutions to common issues to help you make the most of your experience on the server. Mod Tutorials

Angle Snap

The Angle Snap feature is only useful if you're using the machine shown in this video: 💡 Automatic Rotation Machine – YouTube.

This option locks object rotation to predefined angles, making movements more precise and aligned. By default, it can be toggled on and off with the F6 and F7 keys. It's ideal for maintaining symmetry or working on structures that require exact rotations.

Carpet Mod (Server and Client)

Carpet Mod is an advanced tool for testing, optimization, and full world control in Minecraft, whether you're playing in creative or technical mode. It works both on the client and the server.

Some useful commands:

• /player Rusbik spawn and /player Rusbik kill: Spawns and removes bots with basic AI. Useful for simulating players.

• /carpet viewDistance 10: Sets the server’s simulation distance to 10 chunks. Use with caution, as it can cause significant lag.

• /log mobcaps: Displays the number of active mobs by category and dimension.

• /log tps: Tracks the server’s real-time performance (Ticks Per Second).

• /fill: A creative tool to quickly fill areas—ideal for performance testing or building.

There are many more commands and advanced settings available. Use /carpet in-game to explore them all.

Flashback

Flashback is a tool for recording and replaying in-game replays, perfect for analyzing movements, recording content, or reviewing mistakes.

To use it, open the menu with ESC and click the Record button. You can start and stop recordings at any time.

Litematica

Litematica is a mod that allows you to load builds (schematics) into the world, helping you build with precision using a visual guide.

Press M to open the mod’s main menu.

From there, you can easily select, load, and manage schematics.

In episode 23 of the project, Rubik will give a short explanation (coming soon).

Syncmatica

Syncmatica is an extension of Litematica that allows you to share schematics in real time with other players on the same server.

Open the menu with M.

Go to Schematic Placements and select your schematic.

Set it to Locked so it can’t be modified.

Then, in the same menu, Shift + Click on “Share” to share it with other players.

This makes teamwork much easier, as everyone can see and build from the same visual guide.

MiniHUD

MiniHUD is a mod that displays useful information about the world in a visual and customizable way, like a "mini F3" screen.

Open the menu with H + C.

You can activate various visual overlays, such as:

• Light levels

• Slime chunks

• World spawn chunks

• Structure boundaries

• .mca file regions

• Shapes like circles and spheres

Perfect for building, efficient lighting, or advanced technical work.

Tweakeroo

Tweakeroo is a mod packed with small improvements (“tweaks”) that enhance both technical and creative gameplay in Minecraft.

Open the menu with X + C to configure or activate tweaks.

Some highly recommended and useful tweaks (used by Rubik):

• tweakFlexibleBlockPlacement: Allows placing blocks at flexible angles. → Also enable the hotkeys FlexibleBlockPlacementOffset and FlexibleBlockPlacementRotation, and assign keys to them.

• tweakFreeCamera: Activates a free spectator-style camera. → It’s recommended to assign a key like Ç for this.

• tweakGammaOverride: Lights up the world 100%, like having constant night vision. → You can use * to toggle it.

• tweakHandRestock: Automatically restocks items in your inventory when they break or run out.

• tweakShulkerBoxDisplay: Shows the contents of shulker boxes when hovering the cursor over them.

⚠️ Make sure to activate each tweak individually for them to work properly.

How to Manage Your Server

When you purchase your server, you will receive an email with the receipt and login credentials for the control panel. Installation can take up to 10 minutes.

This panel gives you full control to customize your SAER2 server, although it comes preconfigured so you can start playing right away. If you choose to make changes, keep in mind it’s recommended only for advanced users, as mistakes could affect the server’s performance.

If you have any questions, HolyHosting’s technical support team is available to assist you.

3. Common Issues

"This server requires you connect with Velocity"

This error occurs because your plan is the Advanced one (which includes Creative and Survival), and you are trying to connect directly to the Survival or Creative server.

In your Holy control panel, you’ll see three servers: Creative, Survival, and Proxy. The Proxy is responsible for connecting both servers, and that’s the one you need to join. For security reasons, it’s not possible to connect directly to Survival or Creative.

First, connect through the Proxy, then use the command /server creativo to switch modes if you want. Also, if you want to use a subdomain without a port (like yourserver.holy.gg), you’ll need to configure it through the Proxy, since it’s the main entry point.

If you’re already connecting correctly through the Proxy and the error persists, don’t hesitate to contact us—we’ll be happy to check it out as soon as possible.

My SAER 2 server won’t start

Common causes:

• Mod conflicts or incorrect mod versions

• Syntax errors in files like carpet.conf

• Corruption in custom configurations of mods like Syncmatica or Litematica

Solution:

• Check the log (latest.log) from the HolyHosting panel to see exact errors.

• Make sure all mods are for version 1.21.4 (as they should be).

• If you added or changed anything in carpet.conf, Litematica, or Tweakeroo, try restoring a previous backup or deleting the config so it regenerates.

• Try starting the server without new mods if this happened after a recent installation.

General Lag / Low TPS

Common causes:

• Too many entities or blocks with heavy rendering

• Mods like Litematica displaying many complex schematics

• High chunk view distance set by Carpet (/carpet viewDistance)

Solution:

• Use /log tps or /tick health with Carpet to identify which part of the tick is slow.

• Reduce /carpet viewDistance to 6 to maintain a good balance.

• Ask players to use MiniHUD or EntityCulling to reduce client-side load.

• Use FerriteCore, Krypton, and Sodium (already installed) to keep memory and network usage under control.

Issues Connecting to the Server

Common causes:

• Incorrect IP or port (or custom IP/subdomain)

• Server crashed or is offline

• Server is still installing

Solution:

• Make sure the server status is "online" in the control panel.

• Verify that the IP address and port are correct (from the panel).

• If the issue persists, contact technical support.
