Immersive worlds.
Sovereign infrastructure.

Enterprise VR experiences powered by local AI — training simulations, cultural exhibitions, virtual showrooms and live event stages. Built on Unreal Engine 5, rendered on your hardware.

I · CAPABILITIES Not a demo. A production environment.

Not a demo.
A production environment.

A

Unreal Engine 5 Pipeline

Full UE5 rendering pipeline for photorealistic environments. Nanite geometry, Lumen lighting, virtual production workflows. Cinema quality at interactive framerates.

B

AI-Driven NPCs

MetaHuman avatars with real-time conversation, emotion and lip-sync. NPCs that listen, understand and respond — not scripted, but genuinely interactive.

C

Spatial Audio

3D audio with HRTF rendering, room acoustics simulation and voice agent integration. Hear the guide behind you, the crowd around you, the whisper beside you.

D

Multi-User Sessions

Shared VR spaces for teams, classrooms, audiences. Synchronized state, voice chat, avatar presence. Train together, explore together, present together.

E

Hardware Flexibility

Meta Quest, HTC Vive, Varjo, PCVR, desktop and mobile. One experience, every endpoint. Adaptive quality scaling from standalone headset to RTX workstation.

F

On-Premise Streaming

Cloud-free VR streaming from your data centre. Pixel streaming for thin clients, local rendering for maximum fidelity. Zero dependency on external infrastructure.

II · USE CASES Where immersion creates value

Where immersion
creates value.

CASE 01

Immersive Training Simulations

High-risk scenarios without real-world risk. Healthcare procedures, emergency response, industrial safety, military training. AI instructors that adapt to each trainee, provide real-time feedback, and document performance.

CASE 02

Virtual Exhibitions & Cultural Experiences

Walk through ancient civilisations, explore architectural models, visit museum collections. AI guides that speak your language, answer your questions, adapt the tour to your interests. Aethos showcase: Labyrinth — Minoan civilisation VR experience, built by STK Engineering as an internal demonstration.

CASE 03

Virtual Showrooms & Product Demos

Configure cars, walk through buildings, inspect machinery — at 1:1 scale, from anywhere. Sales teams present remotely with the same impact as on-site. Reduce travel, accelerate decisions.

CASE 04

Live Event Stages

VR stages for conferences, product launches, award ceremonies. AI co-hosts, interactive audiences, hybrid physical-virtual formats. Proven at scale: polySTAGE at Austria Center Vienna, BEA World 2× Gold.

III · THE PIPELINE From concept to presence

From concept
to presence.

01

Environment Design

Concept art, spatial planning and world-building for the target experience.

02

Asset Pipeline

3D modelling, Nanite-ready meshes, material authoring and Lumen-lit scenes.

03

AI Integration

NPC behaviour trees, conversational agents, spatial audio and voice pipelines.

04

Multi-User Setup

Session management, state synchronisation, voice chat and avatar replication.

05

Hardware Deployment

Device provisioning, pixel streaming configuration, adaptive quality profiles.

06

Live Operation

Monitoring, analytics, content updates and on-premise infrastructure support.
