Who We Are
Precision for the studios that dare.
Invisible Wall, S.L. is a Barcelona studio for game development and interactive production. Our team carries AAA shipping experience from years on major commercial titles, applied today across outsourcing and consulting for video games, interactive applications, VR experiences, visualization for fairs and museums, and film. iGaming is where we are currently shipping, on Invisible Engine — our own game runtime and studio pipeline. In parallel, we are developing our own original game IP.

Games We Have Produced
Slots built on our own engine and pipeline, and an original multiplayer game of our own. Every in-game screenshot below is captured from the running game, not a mock-up. Slot demos run on our test server with play money.
Book-of Slot · Operator Build
Book of Far West
A Wild West take on the Book-of format. The book symbol is both wild and scatter; three or more open a free-spins round with an expanding special symbol. The free-spins trigger plays a fully authored cinematic before the award screen. Shipped as an embeddable operator build that drops into the partner's existing casino page.

Ways Slot · Built in the Pipeline
Ways on Waves
A high-seas ways slot on a stepped board: five reels of 3, 4, 4, 4 and 4 rows. Scenes, symbols, flow and win presentation were authored in the Invisible studio tools rather than hand-coded, making it the clearest example of how fast the pipeline turns a concept into a playable game.
Our first title on the engine: a fruit paylines slot adapted onto our stack and connected to the partner's remote game server. Its symbol atlases were regenerated through our AI-assisted atlas pipeline while keeping every Spine animation intact — the workflow that later became the Invisible Pipeline.

Original Game · Online Multiplayer
Salmons!!!
Our own browser game: up to 100 players share one river. Swim upstream as a salmon, or play the catchers — a fisherman on the bridges or a bear on the banks. Every match is a newly generated river with meanders, waterfalls and bridges, run on an authoritative real-time server.
Production-grade disciplines we own in-house. They transfer cleanly across video games, interactive applications, VR, visualization, and film — wherever a client needs them.
01
Core Discipline
3D Art Production
Full-cycle 3D asset creation — modeling, sculpting, retopology, UVs, texturing, integration. Hard-surface and organic, environment and prop. Calibrated to your render path — real-time engine, VR, interactive build, or offline cinematic — and to your stack, style guide, and performance budget.
Character and creature rigs — biped, quadruped, custom skeletons. FK/IK control systems, facial setups, blend shapes, deformation tuning. Engine-ready exports for Unreal, Unity, custom engines, and animation pipelines.
Biped/QuadrupedFK / IKFacial RigsBlend Shapes
03
Character & Creature Art
End-to-end character and creature production. Concept-to-asset pipeline: high-poly sculpt, retopology, texturing, hair and grooming where needed. Stylized or realistic, calibrated to budget and render context.
CharactersCreaturesStylizedRealistic
04
Performance Optimization
Profiling, draw-call reduction, memory tuning, asset and scene-level optimization. Bottleneck triage on PC, console, mobile, web, and VR. We diagnose, fix, and hand back documented changes.
ProfilingMemoryMulti-PlatformVR-Ready
05
Tech Art
Shader authoring, VFX graphs, procedural tooling, runtime performance work. The bridge between art and engineering — where most production headaches get solved before they ship.
ShadersVFXProceduralTools
06
Pipelines
Custom asset pipelines, automation tools, DCC integrations, validation systems. Built for art and animation teams that need their workflow to scale without breaking.

07
Production Consulting
Technical reviews, art direction audits, scoping for outsource arrangements, strategic guidance for studios scaling their pipeline or onboarding new disciplines. Practical advice grounded in production experience.

What We Can Do
Capabilities
The full art-to-frontend stack we deploy across both tracks — client work and our own original IP.
Modular kit design through full scene dressing — game levels, VR spaces, museum walkthroughs, architectural visualizations. We design, model, texture, and integrate into your render path, respecting every technical constraint.

Character Pipeline
Character Modeling & Rigging
End-to-end character production: high-poly sculpt, retopology, texturing, hair/grooming, and engine-ready rigging with FK/IK, facial setups, and blend shape libraries — for real-time games, VR avatars, or offline animation.
MayaZBrushBlenderSubstance
03
Materials
PBR Texturing & Material Creation
Physically-based materials for any render pipeline — albedo, roughness, metallic, normal, AO, and custom channels. Substance Painter and Designer for procedural workflows; hand-painted alternatives when stylization calls for it.

Visual FX
Custom Shaders & VFX Development
Bespoke shaders in HLSL, Unreal Material Editor, or Unity Shader Graph — NPR, toon, water, foliage, surface effects. Niagara and VFX Graph particle systems calibrated to the runtime budget of the platform.

LOD & Performance Optimization
Asset- and scene-level optimization — polygon reduction, LOD chains, draw-call batching, texture atlasing, occlusion culling. Frame-rate stability on PC, console, mobile, web, and standalone VR headsets.

Automation
Pipeline & Workflow Automation
Custom Python tools for Maya, Blender, Houdini, and your engine editor. Automated import/export, asset validation, and batch processing — so the team stops doing manually what a script can own.

Scalable Co-development Support
We embed into your workflow as a clean extension of the team — adapting to your tools, version control, naming conventions, and review cycles. Scale the engagement up or down as the project demands.

The Invisible Pipeline
Our own engine. Our own studio tools.
Invisible Engine is the game runtime we build every title on. Around it sits an online studio of around twenty in-house tools, opened from one launcher, that cover a game from math to art, animation, audio, localization and delivery. Artists, animators and developers author in the browser; the game reads that work live, so most changes reach a playable build without a line of code.

What It Lets Us Build Fast
From idea to a playable link, without starting from zero.
Mechanics live in the shared runtime, so a new title is mostly configuration and art. Publishing is a data operation, not a rebuild: the result is a link a client can play the same day.
Reskins & re-themesNew art on a proven math model, with symbols and atlases regenerated through the AI pipeline.
New slots from built-in mechanicsLines, ways, Book-of, cascades (tumble), multiplier collect, cluster and scatter pays, stepped grids.
Feature presentationFree-spin intros, big wins and character moments authored as cinematics, not hand-coded.
Prototypes & pitchesA playable concept on our test server to validate an idea with a partner before full production.
Operator deliveryAn embeddable build that plugs into the operator's own page and game server, in their languages and currencies.
iGaming
Casino content, built like video games.
iGaming is where we ship today. We bring the production habits of video-game development — engine, tools, animation craft, automated QA — to slot content for regulated operators.

Vision
Closing the gap with video games
Most slots still look and feel a generation behind the games their players know. We want to close that gap — in how games are made and in what players experience.
ExecutionA real production pipeline: versioned tools, shared runtime, live authoring, automated playtesting. The discipline of a game studio applied to casino content.
Characters & storyRigged characters, directed cinematics and a world around the reels — already running in Book of Far West.
New board languagePerspective boards where symbols emerge in place, stepped grids, cascades: layouts that move beyond the rectangle of reels.
ResultsGames players remember and return to, produced at a pace and cost that make that quality viable for every title.
