From sketch to animation or video game: what changes when a visual idea has to move and respond
A sketch can define the appearance of a character, an object or a setting, but it does not yet contain all the information needed to produce it. In animation, it will need to be developed into shots, poses, timing and movement. In a video game, it must also be integrated into a system with states, rules and technical constraints. There is a chain of translations between the visual idea and the final result.
The same sketch can have two very different futures
Imagine a single image: a character stands still in front of a huge red door at the end of a dimly lit corridor.
That drawing clearly establishes a silhouette, a sense of scale, a colour contrast, a lighting atmosphere and certain clues about the world to which it belongs. As a static piece, it works. It conveys tension, weight and mystery. However, the moment that image leaves the sketchbook or tablet to enter a production environment, its apparent self-sufficiency vanishes.
If that idea is destined to become an animated scene, the team needs to answer questions that the sketch does not resolve:
- From which camera angle will we reveal the door?
- How long does it take the character to walk down the corridor?
- Does the character hesitate before taking the first step, or do they move forward with determination?
- In which frame does the music change or the ambient sound fade out?
- What does the reverse shot reveal when the camera decides to cut?
If that same image is intended to become an interactive experience within a video game, the questions multiply in a different direction:
- Can the player decide not to approach the door and explore the side walls instead?
- Is the door closed, ajar, blocked by a mechanism, or ready to be broken down?
- What visual, auditory or physical response does the user receive when standing in front of it or pressing a button?
- What happens if they return to that very spot hours later, after the environment has changed?
- Is the outline of the door still recognisable when the camera zooms out to the edge of the frame?
The drawing may be exactly the same. The production questions are not.
Concept art is not the polished end result of an idea
In the contemporary creative ecosystem, it is common to confuse a promotional illustration with concept art. Social media and art books frequently showcase polished pieces, rich in detail and finished with spectacular lighting. But the role of a concept artist in an actual production is not to deliver a definitive picture to be framed.
Their real aim is to reduce the technical and narrative uncertainty faced by the departments that come next.
An audiovisual or interactive project does not always begin with concept art; it often stems from a literary script, a mechanical requirement for game design, anthropological research or a rudimentary grey-box prototype. When concept art comes into play, it acts as a deliberate tool for visual exploration. It establishes scale proportions, tests silhouette variations, defines plausible materials, researches architecture and establishes colour palettes that convey the required emotion.
That is why the professional question that validates a piece of concept art is never ‘Is it pretty enough to publish?’, but rather: what information does the next person on the team need to extract from this image in order to do their job? If the 3D modeller does not understand the construction plans, if the rigger cannot intuit how the shoulders interact with the clothing, or if the level designer cannot distinguish which areas are navigable, the artwork will have failed in its practical purpose, regardless of its technical virtuosity.
When an image enters the realm of time, it is no longer enough for it simply to work when still
When a visual idea takes the path of animation, the first challenge it faces is time. An illustration exists in a continuous present; it does not need to resolve what was happening half a second earlier or where the gaze is directed half a second later. In a film or television scene, by contrast, the image is broken down into sequence, duration, acting, editing rhythm and staging.
For the static idea to survive the temporal dimension, the production pipeline relies on successive layers of visual translation.
The storyboard transforms intention into sequence
The storyboard is neither a comic strip nor a simple illustrated guide to the script. Its role is to transform a dramatic or narrative intention into a strict succession of decisions regarding camerawork and composition. Here, the type of shot (ranging from a suffocating close-up to a descriptive long shot), the spatial relationships between characters, the entries and exits from the frame, and the editing cuts are established.
The specialist storyboard artist checks whether the script’s tension is sustained visually from shot to shot or whether spatial continuity is disrupted, deciding what information the viewer should see and, just as crucially, what information should be concealed from them.
The layout turns a sequence into a producible shot
Whilst the storyboard determines what should happen visually, the layout begins to specify how that decision fits within the actual shot that will need to be produced.
At this stage, the abstraction of the sequential sketch comes up against the real-world scale of the set, mathematical perspective, the lens’s focal length and the three-dimensional positioning of the characters. The layout defines the technical set design: it ensures that the chosen lens does not distort the background in an undesirable way, that the set elements leave enough space for the characters to perform, and that the animation department is provided with a workspace featuring dimensions, depths and boundaries defined down to the millimetre.
The animatic forces the image to occupy time
The translation into time undergoes its first major test with the animatic: the chronological assembly of the storyboard panels accompanied by provisional tracks of dialogue, sound effects and music.
It is here that the drawing acquires a real physical duration. Suddenly, problems that were invisible on paper emerge: a static shot that seemed dynamic turns out to be unbearably long on screen; an emotional reaction lacks the necessary frames for the eye to process it; or a rapid transition undermines the clarity of the action. The animatic provides information on running time and pacing. It establishes durations before hundreds of hours are spent modelling or animating unnecessary frames.
A drawn character is not yet an animatable character
Seeing a character finalised on a model sheet conveys a false sense of completion. There is the front view, the side view, the three-quarter turn and an expressive selection of facial expressions. However, in visual production, a drawn figure is merely a visual concept that cannot yet move with organic fluidity.
For a 2D or 3D design to come to life without breaking, it must undergo the rigging process. Far from being reduced to the cliché of ‘putting virtual bones on a puppet’, the rig is a complex architecture of mathematical relationships, deformers, constraints and control hierarchies designed to enable the animator to manipulate the digital puppet in an anatomical, expressive and consistent manner.
A brilliant conceptual design can turn into a production nightmare if it hasn’t taken into account how volumes react in space:
- How do the rigid shoulder pads bend when the character raises their arms to climb?
- Does the anatomy of the torso allow it to rotate without the clothing passing through the body’s geometry?
- Does the face have the necessary muscular flexibility to shift from irony to panic without aberrant deformations?
Designing for movement requires anticipating deformations, articulations and torsion limits long before asking the model to deliver a line of dialogue or perform a stunt on screen. If this mechanical translation is not considered right from the character design stage, the expressiveness of the acting will be compromised by the structural limitations of the asset itself.
When the image can respond, it is no longer enough simply to design what will be seen
At this point in the journey, the interactive fork takes a definitive step away from linear audiovisual media. Video games also contain cutscenes, acting and meticulous animation, but the nature of the medium imposes an additional requirement: control passes into the hands of another person.
In animation, an image must stand the test of time. In an interactive experience, it must also withstand the actions of the participant.
In a film production, the team decides what the viewer sees and for how many seconds they see it. In a game or real-time experience, the image must be broken down into a sequence of states. It is no longer a question of designing a specific moment frozen in a frame, but of defining how that element exists at rest (idle), how it transitions to movement when a key is pressed (walk/run), what happens if it receives an unexpected impact (hit reaction), and how it recovers when returning to a state of calm.
The same logic applies to elements of the environment:
- The door in the corridor is no longer just a drawing: it is a programmable object that can be closed, jammed, unlocking or destroyed.
- A light source is no longer a coloured line: it is a dynamic light source that can be switched on, flash or cast shadows in real time depending on the user’s position.
Interactive production requires more than just images: it requires images capable of forming part of a system of states interconnected by logical and physical rules.
A video game environment must also allow for gameplay
A digital environment cannot be judged solely on its compositional beauty. In video game development, environment art and level design must tackle a shared challenge: the functional habitability of the scene.
A conceptually stunning setting can prove to be a production failure if it creates visual noise:
- When background textures clash in contrast with the silhouettes of enemies.
- When a ledge that appeared climbable turns out to be a purely ornamental element that collides with an invisible wall.
- When ambient lighting fails to guide the player’s gaze towards the natural exit from the room, leaving them completely disoriented.
The camera accentuates this difference. Whilst in an animated feature film the camera shot is fixed and allows only what is within the frame to be optimised, in many 3D video games the player can move close to a wall, view the models from the floor, or rotate the viewing angle towards the ceiling. The 3D asset must retain its formal coherence, scale and visual density from an unpredictable viewing range, whilst maintaining absolute clarity in the service of gameplay.
The engine is not the place where you ‘plonk the art’ in at the end
There is a common misconception that a game engine is a passive container into which models, textures and audio are dumped once the artists have finished their work. The technical reality is quite the opposite: integration into the engine determines, from day one, how modelling is carried out, how it is optimised and how it is rendered.
Within the engine, various factors converge that directly impact the visual appearance of the game:
- The frames per second and graphics memory usage.
- The number of polygons that can be displayed on screen without compromising performance.
- The resolution and compression of texture maps.
- Geometric collision calculations and static or real-time lighting calculations.
It is at this point of operational friction that the role of the technical artist comes to the fore. A technical artist works at the intersection of artistic requirements and the technical constraints or tools that enable that content to function within the production. Far from being a mere ornamental or rigid role, they act as an interdisciplinary bridge: they design shaders, automate import workflows, fine-tune particle systems and optimise polygon meshes to ensure that the art direction retains its visual magic without exceeding the platform’s processing budget.
What is lost when an idea is poorly translated
When a production fails, it is rarely due to a lack of initial artistic talent. Bottlenecks and friction arise from what is known in the industry as ‘translation losses’: decisions made at an earlier visual stage that prove unworkable when translated into three dimensions, motion or in-engine interaction.
A design can become unusable for production for various reasons:
- It works visually from a single, fixed perspective, but breaks down as soon as the camera rotates in three dimensions.
- It incorporates micro-details that disappear completely at the game’s native resolution or obscure the silhouette at medium range.
- It requires a level of geometric complexity that slows down the engine’s overall performance or prevents clean mesh deformation.
The problem is not that the idea changes during production. The problem is not knowing which part of the idea should survive the change.
To prevent a work from losing its soul along the way, professional teams constantly distinguish between what is essential and what is negotiable in every visual decision.
Let’s consider a recurring example: a character conceived in concept art with a majestic, flowing cloak. That cloak was incorporated by the concept artist because it conveyed hierarchical status, mystery and an imposing silhouette.
When moving into 3D production and animation, the cloak begins to cause problems: it passes through the geometry of the sword on the character’s back when they turn (clipping), obscures the subtle movements of the arms during acting, and covers the attack warning animation in the midst of interactive combat.
A department’s simplistic response might be to remove the cloak; the professional approach is to ask: what was the core function of that garment? If the aim was to lend presence and volume to the character’s silhouette, it could perhaps be replaced by a wide fur collar, a structured waistcoat or an asymmetrical semi-tunic that allows the arms and joints to be clearly seen.
The essentials (personality, dominant silhouette, visual hierarchy) are preserved. The negotiable elements (fabric length, full physical simulation, joint coverage) are redesigned to serve the production.
There is no universal pipeline
The workflow in the digital industry is often presented as an immutable mathematical formula. However, there is no single, closed pipeline that works equally well for a 3D animated film, a 2D cut-out series, an indie video game developed by five people, or an interactive blockbuster involving hundreds of developers.
What does exist is a rigorous architecture of dependencies: knowing which decisions must be made and validated with sufficient technical certainty before allowing the next department to begin building upon them.
A pipeline is not a creative recipe: it is a way of organising dependencies so that many people can build the same work without working in the dark. Technically, a production pipeline is the organisation of the workflow through which an idea passes through different departments, tools, deliverables and reviews until it becomes a producible result.
A documented example of a technical pipeline for the production of real-time cutscenes in the video game industry — such as the workflows presented at the Game Developers Conference (GDC) and technical guides on in-engine capture and sequencing — sets out a specific sequence of successive validations:
Script and scene concept: a dramatic definition of the sequence’s narrative and gameplay objectives.
Storyboard: breakdown into shots and key visual intentions.
Layout / 3D Blocking: positioning of virtual cameras, set volumes and spatial cues for the characters.
Motion capture (MoCap) or keyframe-based animation: generation of physical and facial acting.
Technical animation and cleanup: fine-tuning of weighting, ground contacts and resolving clashes with costumes or props.
Integration into the engine’s sequencer: synchronisation of animation tracks, sound events, virtual cameras and visual effects.
Cinematographic lighting and real-time render pass: final aesthetic adjustments, exposure control and validation of technical performance on the target hardware.
It is worth emphasising that this workflow represents an example of a pipeline for a very specific format and not ‘the general industry pipeline’. If the project were a traditional frame-by-frame hand-drawn animation production or an isometric strategy video game, the hierarchy of phases, tools and reviews would change substantially to accommodate its own logical dependencies.
Animation, Digital Art and Video Game Design: three ways of engaging with the same ecosystem
When a young person feels a calling towards drawing, character design or virtual worlds, they tend to group all these areas under a single intuitive umbrella: ‘creating visual stories’. However, upon adopting a more professional perspective, it becomes clear that engaging with this chain of translations requires developing formally distinct ways of thinking.
Within the university educational framework, this reality translates into three complementary approaches that reflect how problems are divided in development studies:
- The Bachelor’s Degree in Animation focuses on shot composition, dramatic interpretation, rhythm and audiovisual timing. Its scope of work delves into how an idea is transformed into a storyboard, layout, rigging, 2D or 3D animation, cinematic lighting and scene composition.
- The Bachelor’s Degree in Digital Art and Visual Creation for Video Games and Interactive Environments addresses the comprehensive construction of the visual assets and stylistic language that populate an interactive world: from the conceptual art of characters and settings to digital sculpting, high-precision 3D modelling, advanced texturing, user interfaces (UI) and in-engine art direction.
- The Bachelor’s Degree in Video Game and Virtual Environment Design and Development focuses on rule architecture, game mechanics, level design, prototyping and in-engine system programming, defining the behaviours, states and physical responses that underpin the gaming experience.
These three perspectives are constantly intertwined in a production, but they do not address the same type of problem: one organises movement and staging; another constructs the language and visual assets; and the third defines and develops the systems through which that experience responds. Of course, professional and academic boundaries are not completely watertight: the most cutting-edge production teams stand out precisely because of their ability to engage in interdisciplinary dialogue through this shared technical vocabulary.
The sketch was the beginning of a conversation, not the end of an image
Being able to draw well is a brilliant starting point, but production goes far beyond simply finishing a line. When an illustrator or concept artist realises that their sketch is not the final work, but rather the foundational blueprint to be interpreted by modellers, animators, level designers or programmers, their way of thinking about the image changes radically.
They stop evaluating their drawing as an isolated image and begin to envisage the reverse side of the shapes, the mechanics of the joints, the response to movement, the clarity of states and the demands of a real-time engine.
A visual idea does not progress towards production through mere accumulation: it is translated. And with every translation, it must prove that it still works.
A sketch may be the starting point for a scene, a playable character or an entire world, but each destination demands different decisions. Explore UDIT’s Animation and Video Games programme and discover which part of that transformation you’d like to learn to build upon.
