3D rendering brief: what it is and what to send

A 3D rendering brief is the set of information and files that the client provides to the studio so that the images, videos or tours can be produced. It brings together the technical project, finish choices, style references and the objective of each piece. It is from this that the studio builds the 3D model, defines the framing, chooses the lighting and decides what each image needs to communicate.

A complete brief is not bureaucracy. It is what separates a project that moves forward in a straight line from a project that goes back several times to the same stage.

What to send in the brief

Technical project

• Floor plans for all floors that appear in the images, with dimensions and room names.
• Sections with level dimensions, to define ceiling heights, slabs and the relationship between floors.
• Elevations with indication of materials, frames, brise-soleils, guardrails and key elements.
• Site plan with the site, access, setbacks and solar orientation (north).

Ideally, send editable files (DWG, RVT, SKP, IFC) in addition to the PDF. An existing BIM or 3D model speeds up modelling, even if it needs adjustments for rendering.

In practice: Render Fabrik is a 3D architectural rendering studio working with clients in Brazil and Europe, with a quote within 24 hours.

Landscape and interiors

• Landscape design with species, external flooring, street furniture, lighting and water features.
• Interior design for the spaces that will be shown: furniture layout, joinery, light fixtures, ceilings and finishes.

When there is no interior design, the studio can propose the decoration, but this must be agreed in advance, as it becomes an additional approval stage.

Finishes specification

The specification describes each material: floor, wall, worktop, sanitary ware, fittings, frames. If possible, include manufacturer, range and colour. This prevents the render from showing a porcelain tile or paint that does not match what will be delivered, which, in sales material, can cause problems with the buyer.

Visual references

Reference images say more about expectation than any description. It is worth sending examples of mood (late afternoon light, cloudy day, night-time), decoration style, colour grading and framing. Pointing out what you like in each reference, and what you don't, helps even more. The studio's portfolio also serves as a starting point for this conversation.

Target audience for the development

Who will buy changes the image. A high-end launch, a compact for investors and a residential for families require different decoration, occupancy of spaces and narrative. The people placed in the scenes, the objects and even the time of day should align with this audience.

Desired viewpoints

List the views you need: main facade, access, swimming pool, function room, living room of the show unit, view from the balcony. If there is a position that enhances the site, such as a sea view or a park view, indicate it. A simple mark-up on the floor plan, with arrows showing the viewing direction, resolves many questions.

Usage format

Say where the pieces will be used: website, social media, adverts, printed brochure, exhibition stand panel, billboard. This defines resolution, aspect ratio (horizontal, vertical, square) and even framing, because an image designed for Stories needs to be composed differently. The same applies to 3D video and virtual tours: duration, display platform and presence of voice-over or subtitles.

Common mistakes

• Sending outdated project versions. The modelling is done based on the wrong plan and needs to be redone.
• Leaving finishes until later. The studio has to assume provisional materials, and changing them later creates new rounds.
• Asking for "a nice image of the facade" without saying for what use, at what time of day and with what mood.
• Comments from several people without consolidation. Architect, developer and marketing ask for different and contradictory things.
• Changing the project during production without recording what changed. Project alteration is different from revision and affects the schedule.
• Omitting the surroundings. Without photos of the site and neighbouring buildings, the render may show a landscape that does not exist.

How the brief affects timeline and outcome

The timeline of a rendering project depends less on production speed and more on the amount of back and forth. Every piece of information missing at the start becomes a question during modelling, an assumption by the studio or a correction after the first preview. A complete brief reduces revision rounds to the part that really matters: fine-tuning light, colour and composition.

The outcome also changes. When the studio knows who the image is for and where it will be seen, decisions about framing, occupancy and mood stop being generic and start serving the commercial or presentation objective of the project. For architects, the brief is the way to ensure that the representation respects the design intent; see how we handle this stage on the page for architects. If you already have the material gathered, send it via contact.

Frequently asked questions

Can I start without the interior design?

Yes, as long as this is agreed. The studio proposes furniture and finishes, and this proposal goes through approval before the final image. This adds a stage, but avoids stalling the project.

In what format should I send the files?

Editable files (DWG, RVT, SKP, IFC or similar) together with the PDFs. The editable file allows extracting measurements and geometry accurately; the PDF confirms which is the official version of the project.

Can the brief be changed after production starts?

Yes, but each change must be recorded in writing. Finish adjustments are included in revisions; changes to floor plans, facades or massing are usually treated as project alterations and affect the schedule.
