Unity and Unreal development, for games and beyond
Gjethe develops real-time 3D applications in Unity and Unreal Engine: games, product configurators, training simulations, architectural and real estate visualisation, digital twins, interactive installations and AR or VR apps. We choose the engine that fits your platform and team, optimise for the target devices, and hand over a clean, documented project you own.

Definition
What is unity & unreal development?
Unity and Unreal Engine are real-time 3D engines: software that renders interactive 3D scenes many times per second, used for games and increasingly for configurators, simulations, visualisation and XR.
Game engines have become general-purpose tools for anything interactive in 3D. A furniture brand can let customers configure a sofa in real time, an engineering firm can train staff on a virtual machine, and an architect can walk clients through a building that doesn't exist yet. The engine handles rendering and physics; the craft lies in building the experience, optimising it and shipping it to the right devices.
Who is it for?
Game studios and indie developers
Extra engineering capacity, prototypes, ports and optimisation.
Product brands
Real-time configurators that show every colour, material and option.
Industrial and training teams
Simulations and digital twins for training, planning and sales.
Architecture and real estate
Interactive walkthroughs and visualisations of unbuilt spaces.

Unity or Unreal?
| Unity | Unreal Engine | |
|---|---|---|
| Strengths | Mobile, AR, cross-platform, large plugin ecosystem | High-end visuals, cinematic lighting, large worlds |
| Language | C# | C++ and Blueprints |
| Web builds | Mature WebGL and WebGPU support | Limited; pixel streaming for the browser |
| Typical fit | Mobile games, AR, configurators on many devices | Architectural visualisation, PC and console, virtual production |
Beyond games
Most of the same techniques that make a game feel good make a configurator or simulation feel good: responsive controls, smooth frame rates, clear feedback and fast loading. We bring that game-development discipline to commercial projects, from product configurators embedded on a website to training scenarios on a headset.
These projects usually connect to other systems, such as product data from your catalogue, prices from your shop, or results sent to a learning platform, so we design those integrations from the start.
Performance on real devices
Real-time 3D lives or dies by performance. A configurator that stutters on a mid-range phone, or a VR scene that drops frames, loses users quickly. We set performance budgets for each target device, profile on real hardware throughout development and optimise geometry, textures, lighting and code until the experience runs smoothly.
Joining an existing project
Studios often need help with a specific part of a game rather than a whole build: porting to another platform, fixing performance, adding multiplayer, implementing a feature or integrating a third-party SDK. We review the project first, agree a clear scope and follow your team's conventions and version control.
Licensing
Both engines have their own licensing terms and revenue thresholds, which change from time to time. We point out the terms that apply to your project during planning, so there are no surprises at launch. Paid assets and plugins are bought in your name so the licences belong to you.
What helps us start
- The goal and the target devices
- Existing 3D models, CAD files or art
- Design documents or references
- Systems the app must connect to
- Your release channels
- An existing project repository, if any
Product configurators
A real-time configurator lets customers change colours, materials and options and see the result instantly from any angle. It needs accurate models, realistic materials, fast loading and a connection to your product data so options and rules stay correct. Built well, it answers questions that photos can't and reduces uncertainty before purchase.
We can embed configurators on a website, run them on showroom screens or package them as apps, and send the chosen configuration to your shop, quoting tool or CRM.

Tools, and what shapes your quote
Pricing is based on your project and agreed in your quote. These are the things that move it.
| Factor | Why it matters |
|---|---|
| Scope | The number of features, levels or scenes drives most of the work. |
| Art | Creating 3D assets from scratch adds substantially to the project. |
| Platforms | Each additional platform needs optimisation and testing. |
| Visual fidelity | High-end lighting and effects need more optimisation. |
| Integrations | Connections to catalogues, back-ends or learning platforms add development. |
| Multiplayer | Networking adds complexity across the whole project. |
| Area | Tools |
|---|---|
| Engines | Unity, Unreal Engine 5 |
| Languages | C#, C++, Blueprints |
| 3D and art | Blender, Substance 3D, Houdini for procedural assets |
| Pipeline | Git LFS, Plastic SCM or Unity Version Control, Perforce |
Common mistakes to avoid
What we see go wrong most often, and how a good project avoids it.
Choosing the engine by reputation
Pick the engine that fits your platforms and team, not the one with the best trailer.
Optimising at the end
Performance problems found late are expensive. Profile on target devices from the start.
Unlicensed assets
Assets bought by a contractor may not transfer. Buy them in your name.
No version control for large files
3D projects need Git LFS or similar from day one.
Frequently asked questions
Do you build games or only business apps?
Both. We build games and also configurators, simulations, visualisations and XR apps.
Should we use Unity or Unreal?
It depends on your platforms, visuals and team. Unity is often better for mobile, AR and web; Unreal for high-end visuals on PC and consoles.
Can you work on our existing project?
Yes. We review it, agree a scope and follow your conventions and version control.
Can a Unity app run on our website?
Yes, through WebGL or WebGPU builds, optimised for loading time and browser memory limits.
Do you create the 3D art too?
Yes, through our 3D modelling team, or we work with your artists' assets.
Do you publish to consoles?
Console publishing requires developer programme access, which the publisher holds. We can develop and port for consoles in that set-up.
Who owns the source code?
You do, once the project is paid, along with assets created for it.
Can you add multiplayer?
Yes, using networking frameworks suited to the engine and your back-end.
How is Unity or Unreal development priced?
It is quoted on scope, art, platforms, visual fidelity and integrations.
Can you port our game to another platform?
Yes. We assess the project, adapt input, UI and performance for the new platform and handle platform-specific requirements.
Can you optimise a game that runs slowly?
Yes. We profile on target devices and optimise rendering, assets, scripts and memory until it runs smoothly.
Can you build a digital twin of our facility?
Yes. We combine 3D models of the site with live data from sensors or systems, so people can see status and changes in context.
Do you build for mobile as well as PC?
Yes. We optimise separately for each platform, since mobile devices need much tighter budgets for graphics and memory.
Can the app connect to our product catalogue?
Yes. Configurators can load options, rules and prices from your shop or product database so they stay up to date.
