What is Look Development?

The process that determines whether a product render looks photographed or obviously generated, and why it happens before final rendering begins.

The studio behind this guide

The stage most of our work happens in

Look development is where XO3D does the bulk of its work as a director-led product CGI studio: materials built to real physical properties, and lighting built around the product to reveal them correctly. Where a client supplies a physical sample or swatch, the render is compared against it at look-development sign-off. Come to us when the material is effectively the product.

How XO3D compares to the other five supplier models

Look Development (often shortened to Look Dev or LookDev) is the production phase in CGI in which materials, lighting, and environmental context are built and refined until they accurately represent the intended visual result, before any final high-resolution rendering begins. It is the process of making a 3D model look right, not just look like something.

Physically based rendering, explained in the questions below, is the material model behind the image. Use the material-review checklist to record which finish, reference and lighting setup each approval covers before the launch visuals are produced.

At XO3D, Look Development is a dedicated production phase with its own client review stage. Material tests and lighting references are shared and approved before any final render farm time is committed. This is where the visual quality of a project is determined, and where the most important creative decisions are made.

On the Nanuskate ramp animation, Jack Robertson built the composite surface from supplied images because no library material closely matched it. He varied the colour between panels after the first pass read as one uniform surface. The final ramp still and film show the result.

What look dev involves

The three components of look development.

Material Development

Building surfaces from product reference

Materials are developed from the available product photographs, finish specifications and physical samples where supplied. Roughness, metallic response, transmission and surface detail are adjusted against that reference. A suitable library material can provide a starting point; a finish without a close match needs a new material.

Lighting Development

A rig built for this product

XO3D builds a custom lighting rig for every project. No stock HDRIs or preset environments. The rig is constructed to reveal the specific material properties of the product, highlight placement that makes a brushed surface read as brushed, fill light that prevents shadow areas from going flat.

Environment Development

Context that serves the product

The environment, whether studio, lifestyle, industrial, or abstract, is chosen and built to support the product's visual language. Even a "simple studio background" requires precise decisions about light source position, reflection colour, and shadow softness.

FAQ

Common questions, answered.

What is physically based rendering (PBR)?

Physically Based Rendering (PBR) is a computer graphics rendering methodology that simulates the way light physically interacts with real-world surfaces and materials. PBR uses physically motivated models and approximations to describe how surfaces reflect, absorb, scatter and transmit light. The result still depends on the material inputs, lighting and rendering implementation.

Does PBR require the physical product to exist?

No. PBR materials can be constructed from material specifications, finish documentation, and reference samples without the physical product being present. This is what enables XO3D to produce pre-manufacture CGI, we work from engineering specifications to reconstruct the intended material behaviour before the product is manufactured.

When does look development happen in a CGI project?

After the 3D model is built and reviewed, and before final animation or high-resolution rendering begins. The sequence is: model build → model review → look development → look dev review and approval → animation (if applicable) → final render. This order protects production budget, discovering that a material isn't right after final render has run is very expensive. Discovering it at look dev review costs nothing to fix.

How long does look development take?

For a standard product, one or two materials, studio environment, 2–3 working days for the initial look dev pass. Products with complex material mixes (multiple finishes, transparent components, textured surfaces) take longer. Client approval and any revision to look dev takes place before production moves forward.

Do you need a physical sample to develop a CGI material?

Not always. On the Nanuskate modular ramp project, no physical sample was supplied. Jack Robertson built the plastic composite finish from client images and photographs of comparable finishes, then adjusted the colour of individual panels after the first pass looked too uniform.

Production insight from

Jack Robertson

Mid-Level Artist, XO3D

A believable material does not have to be perfectly uniform

In a product material study, Jack found that the first composite surface looked too uniform. He introduced slight colour differences between panels, using photographs of the product and comparable finishes as reference. There was no physical sample, so this was a reference-led visual judgement, not a claim of sample matching.

The useful review question is whether the variation belongs to the material. Check the size of the surface detail, the difference between neighbouring panels and how both read under the intended lighting. More noise is not automatically more realistic.

Keep colour, surface detail and finish controls separate where they need different adjustments. Jack uses masks to isolate these properties rather than forcing every material decision into one diffuse map. Compare the result with the product reference and finish specification before approving the look.
