TECHNOLOGY & IP

Digital-twin and XR technology,
proven by patents

All 14 core and enabling technologies are in-house — zero outsourced development — plus three defense and industrial specializations that even game companies lack. Seven registered and five filed patents protect them.

WHY CRENGINE CAN GO GLOBAL

Game-company-grade technology —
plus the defense know-how games lack

Game-company technology + defense and industrial knowledge and data = the engine of a global company

* CRENGINE's own analysis — scope and level of technology are company assessments.

A · Defense & industrial precision digital twin

Weapon systems and industrial plants rebuilt down to the smallest part (PCB, wiring) — Cheonma, K9 and more.

B · Maintenance-grade 3D object control

Disassemble and assemble by hand or controller without sensors; real equipment logic is reproduced.

C · AI defense solution — knowledge & data

30 years of weapon-system knowledge with data on 822 defense companies and 438 weapon systems.

① LARGE-SCALE VIRTUAL WORLD

A whole city at 1:1 —
large-scale virtual worlds

We reproduced Incheon's 900,000 m² Wolmido as a 1:1 immersive city and built heritage sites, schools and shops at real scale. We also ran the world's first broadcast metaverse (SBS Hope City), linking live broadcast with virtual space.

Wolmido 901,641 m², 600+ buildings, 10,330 m of main roads
PC, mobile and VR share one world; cloud servers sync many users
Korea Industry Fair metaverse expo — 3× KINTEX, 162 companies, 2,000+ products

② PRECISION DIGITAL TWIN & PHYSICS

From the top-level system to the smallest part —
precision digital twins

With 32 years of defense development we rebuilt Cheonma (K-SAM) from exterior to internal parts, because maintenance training needs equipment that is the same inside, not just in appearance.

Circuit-board level, complex internals, real switch and dial behavior
The same 3D assets shared with CBM+ maintenance data
Delivered to the ROK Army Logistics School (2023)

③ 15-PERSON COLLABORATIVE MAINTENANCE

A world-first —
15 people maintain one virtual machine

One instructor and 14 trainees split roles and maintain at the same time — solo self-study, two-person collaboration and 15-person team maintenance put a whole maintenance team on one virtual machine.

In real use at the Army Logistics School special-weapons department
Multi-site remote cross-control patent No. 10-2687406 — a Korean instructor teaches Polish, Australian, Egyptian and Romanian trainees at once
