How to write a 3D rendering brief (free template)

A 3D rendering brief is the document that tells a rendering studio what to show: the project and its purpose, the drawing or model files, materials and finishes, camera views, lighting and mood, output sizes and the deadline. To brief a 3D rendering studio well, fill in each of those eight items before you ask for a quote.

This page is part of our buying guides for 3D rendering. Each section below explains one item of the brief and shows a filled-in example, and the template at the end has one field for each, ready to copy.

What goes in a 3D rendering brief?

A complete brief covers eight items: project summary, purpose and audience, files, materials, camera views, lighting and mood, output, and schedule. Missing items do not stop a studio from quoting; they turn into guesses, and guesses turn into revision rounds.

  1. Project summary. What the building, room or product is, and where.
  2. Purpose and audience. Who will see the images and what they must decide.
  3. Files. Plans, elevations and sections, or the 3D model.
  4. Materials and finishes. Each surface with its product name or code.
  5. Camera views. How many views, marked on a plan, and what each must show.
  6. Lighting and mood. Time of day, season, weather and one reference image.
  7. Output. Pixel or print size, aspect ratio and file format for each image.
  8. Schedule. The final deadline, who approves, and how many review rounds.

A brief also makes choosing a 3D rendering company easier, because quotes from different studios become comparable when every studio quotes from the same eight answers.

Project summary and purpose

State what the project is, who will see the images and what they must decide, because the purpose sets the level of detail. A planning image must match the drawings to the brick course; a sales image must also look inviting at billboard size; a design-review image only needs massing and light. The same building needs a different level of detail in each case.

A filled-in example. "A four-bedroom single-family house on a sloping lot, two stories over a walk-out basement. The images go to the homeowners for sign-off of the exterior materials before the building permit, and then onto the architect's website. They must decide between a cedar and a fiber-cement cladding." Three sentences, and the studio knows the subject, the audience, the decision and the level of accuracy.

Files to send

Send plans, elevations and sections, or the 3D model, in formats the studio can open. A native model saves the most time, because the studio renders the geometry you built instead of rebuilding it from drawings. Our guide to 3D file formats says which to send when you have a choice.

Materials and finishes

List each surface with the product name or code, and attach swatches or a material board. "White tile" has a hundred answers; a product code has one. Where a finish has no code yet, a photo of the sample under daylight works.

Concept work. The materials list becomes the image: every sample on the board appears in the render.

For interiors, an interior design mood board is a good start for this section, because it already groups the finishes and shows how they sit together.

Camera views

Mark each camera on a plan with an arrow and say what the view must show, so the composition is fixed before rendering. A camera arrow takes a minute to draw and saves a revision round, because the most common change on a first draft is "can we see more of the kitchen".

A furnished floor plan with three colored camera cones drawn on it, beside three small renders in matching colored frames showing the view from each cone.
Concept work. Three cameras marked on the plan, and the three views they produce.

For each camera, write one line: where it stands, which way it looks, and the one thing it must show ("from the front door, looking at the fireplace wall, must show the double-height ceiling"). Eye height, corner views and two-point perspective each suit different rooms, and our page on camera angles shows which views work for interiors and exteriors.

Lighting, time of day and mood

Name the time of day, season and weather, and attach one reference image for mood. Light changes a rendering more than any material, and it is the hardest thing to describe in words, so one photo you like does more than a paragraph.

One dining room from the same camera three times: in cool overcast morning light, in warm low golden-hour sun, and at night lit only by the pendant and candles.
Concept work. Same room, three lighting briefs: name the one you want and attach a reference.

If the building's orientation matters, mark north on the plan; a south-facing living room in winter sun and the same room on an overcast afternoon are different images. For dusk and night views, say which lights are on.

Output sizes and formats

Give the pixel size or print size, aspect ratio and file format for every image. An image framed for a wide website banner cannot be cropped to a tall brochure page without losing what the camera was set up to show, so the shape is decided before rendering.

Output by use: choose the aspect ratio for where the image will be used
UseAspect ratioSize and format
Website hero and presentation slides16:9 landscape4K JPG or PNG
Brochure or print boardSet by the page or boardGive the print size; layered PSD on request
Social feedPortrait or square, as the platform shows itJPG
Animation16:91080p or 4K MP4

Our stills are delivered in 4K as JPG and PNG, with a layered PSD on request. Our guide to web and print resolution gives the pixel sizes for each use, and the page on aspect ratio explains how to choose the shape for where the image will be used.

Schedule and review rounds

Give the final deadline, who approves, and how many review rounds you expect. Name one person who approves each draft; comments from three people who disagree are the most common cause of a late final.

Count back from the date you need the finals. With us, a fixed quote arrives within 12 hours of receiving the files, a first draft of stills in 3 to 5 business days, and two revision rounds are included; the delivery date of the finals is fixed in the quote. Animation drafts take 2 to 3 weeks. If the date is close, say so in the brief: delivery in 48 hours is available, subject to capacity. Rates for rush delivery and extra rounds are listed beside each 3D rendering price on our pricing page.

The template has one field for each item above and is the brief we quote from, so a filled-in brief is ready to order. Download the 3D rendering brief template (Word, DOCX), or copy the table below into a document or an email. Fill in each field and paste it into the "What should we render?" box of our quote form; the form asks for your files and contact details on the next step.

Product rendering briefs: what changes

A product brief adds the CAD or sample, exact color references, background and the marketplace image specs. Products are judged at close range, so the brief has to fix what an architectural brief can leave to the studio.

  1. Send the CAD or a sample. A STEP or OBJ file gives exact geometry; without one, send the physical product or photos from every side with measurements.
  2. Give exact color references. Name the color system code for each part, and send a physical swatch where the color is critical.
  3. Describe the material of each part. Brushed or polished metal, matte or gloss plastic, the fabric and its weave.
  4. Choose the background. Pure white for marketplaces and catalogs, or a styled scene for lifestyle images.
  5. List the image specs. Pixel size, aspect ratio and how much of the frame the product must fill, as each marketplace requires.
  6. List the angles and variants. Front, three-quarter, back, detail shots, and every colorway.

Our 3D product visualization service uses this extended brief for white-background images, lifestyle scenes and 360 spins.

Questions

Can I send a hand sketch instead of drawings?

Yes. We accept sketches as PDFs, scans or photos and model from them, as long as the main dimensions are written on. The fewer dimensions there are, the more of the first draft is our interpretation, so mark at least the overall sizes and ceiling heights.

What if my design is not final yet?

Brief what is decided and mark what is open. Layout and camera are checked on a gray clay draft before materials go on, so open questions can be settled on that draft. Two revision rounds are included, so the decisions still open are made on a draft rather than on site.

Do I need to know the camera lens or pixel size?

No. Say where the image will be used and what it must show, and we set the lens and size. The fields on lens and size are there for clients who already know what they need.
