OmniMesh™ – Seamless MMO Networking for Unreal Engine 5

The first true large-scale networking solution for UE5.
Built over 20 years. Proven live. 

Unreal Engine 5 is the most powerful engine for modern games — but until now, it lacked one thing: a scalable large-scale networking solution.
OmniMesh fills that gap — built exclusively for UE5 to power truly massive online worlds.

The scalable MMO backbone powering live worlds and real battles in Unreal Engine 5.

What Makes OmniMesh Ideal for MMO Networking in Unreal Engine 5?

Building a truly scalable MMO is hard.

One of the biggest reasons ambitious MMORPG projects fail is the enormous challenge of building not just a network layer — but the complex systems that power an MMO at scale.

Over two decades, we’ve developed not only OmniMesh, our seamless server mesh solution, but also the core MMO systems needed to run a living, persistent world in Unreal Engine 5.

More than just networking.

OmniMesh isn’t just a network solution — it includes core MMO systems studios typically spend years building:
character architecture, skill trees, crafting, trading, VoIP, login queues, and backend chat brokers.

All of these systems have been developed and tested over decades, dramatically reducing technical risk.
For large-scale studios, they can save years of development and allow teams to focus entirely on gameplay and world-building.

Most “MMOs” aren’t massive.

They split players across shards or instances because Unreal’s built-in networking can’t support large-scale combat. That’s why major sieges cap at ~150 players — and your friends can’t even join if it’s full.

OmniMesh solves this.

Battle-tested in Mortal Online 2, we’ve recorded nearly 500 players in a single, seamless battle, with thousands more active across the open world. All live. All persistent. All without loading, teleporting, or duplication.

Unmatched combat complexity — at scale.

Every strike is performed in real time by the player, with:
• Weapon tracing and accurate collision detection
• Real Projectiles and long-range magic 
• All synced across hundreds of live players in a persistent world, on foot or horseback

It’s not just about numbers. It’s about deep mechanical fidelity — and OmniMesh handles it effortlessly.

Scales up or down.

With simplified visuals or lower real-time logic demands, OmniMesh can scale to even larger battles.

Seamless Server Meshing

Cross-node travel with no loading screens on a continent, no instancing. A unified world.

1000+ Players per Node

True real-time combat with melee traces, parries, ranged, magic, and mounted battles—all synced with precision. No tab-targeting. Every swing and spell is controlled manually. This is one of the most complex combat systems in MMO history, demanding extreme accuracy, collision fidelity, and fast simulation. And it works—even across thousands of players in one seamless world.

Global Ping Normalization

Our custom-built system predicts and syncs fast-paced combat actions across players worldwide—allowing fair melee duels even between EU and US players. It’s a core feature that sets OmniMesh apart in real-time MMO networking.

Minimal servers, Massive worlds

Each node can host hundreds to thousands of players depending on gameplay. Optimized LOD, tick, and packet control reduce hardware needs dramatically.

Smart streaming that scales

Players see castles and characters miles away — but your client and server only process what’s needed.
Our custom network LOD system streams visibility, data packages, and player states at multiple layers (visual, logic, tick), enabling massive battles without choking performance.

Built for UE5 from the ground up

OmniMesh has evolved with Unreal since UE3 — now natively supporting UE5.
