What a 3D Walkthrough Package Includes (and What to Confirm in Writing)

Quick answer: A 3D walkthrough package normally covers modeling, camera path, materials and lighting, rendering, editing and one delivered video in a named format, with a defined number of revision rounds. Still frames, vertical cuts, extra spaces, sound design and model ownership are the items most often assumed but not included. Confirm those five in writing.

This page is a scope checklist rather than a sales page. For the service itself, see 3D walkthrough production.

Normally included

• 3D modeling of the spaces in scope, built from your drawings.
• Camera path design and a blocking pass for approval before final production.
• Materials and finishes applied from your schedule or from agreed reference imagery.
• Lighting for a single agreed time of day or lighting condition.
• Rendering at a stated resolution and frame rate.
• Editing into a single continuous piece at an agreed runtime.
• A defined number of revision rounds, with a written definition of what constitutes one round.
• Final delivery in one named format, usually horizontal video at a stated resolution.

Usually charged separately

None of the following are unreasonable to charge for. The problem is discovering them after delivery, when the leverage is gone.

• Still frames. Images pulled from the same model. Inexpensive when scoped up front because the model already exists. Priced as new work if requested later.
• Vertical or square cuts. Social formats are a separate export and often a separate edit, because a vertical crop of a horizontal camera path frequently does not read.
• Additional spaces or unit types. Each new space is modeling work, not a revision.
• A second lighting condition. Day and dusk versions of the same walkthrough are two renders.
• Sound design or voiceover. Often assumed to be part of a video deliverable. Frequently is not.
• Furniture and styling changes after the material stage has been approved.
• Site context and landscaping if the original scope was interior only.
• Rush handling when a date moves forward after kick off.

The five clauses worth confirming

1. What counts as a revision round

The single most common source of disagreement. A round should be defined as one consolidated set of notes delivered at a defined gate, not as a single change. Without that definition, three emails on three days can be counted as three rounds, and the buyer usually has no argument.

2. How mid production drawing revisions are handled

If your architect issues a revision in week three, is that a revision round, a change order, or absorbed? There is no universally correct answer, but there is a correct time to agree it, which is before kick off.

3. Deliverable formats, listed explicitly

Resolution, frame rate, file format, and every cut you need. Write the list. If a vertical version is required for a paid campaign, it belongs in the contract, not in an email after delivery.

4. Model retention and reuse rights

Ask two questions: does the studio keep the model, and what may you do with the final files. Retention matters because a phase two, a finish update or an interactive version later is cheap if the model exists and expensive if it must be rebuilt. Reuse rights matter because a campaign asset frequently outlives the campaign it was made for.

5. What happens after final delivery

How long files are hosted, whether source files are available, and at what cost. Studios have different policies and all of them are defensible. Not knowing yours is what creates the problem.

Comparing two quotes properly

Put the two proposals side by side and fill in the same eight rows: number of spaces, runtime, resolution, still frames included, vertical cut included, revision rounds and their definition, handling of drawing revisions, and model retention. Price differences that looked arbitrary usually explain themselves within about ten minutes.

If one quote is materially cheaper and matches on all eight rows, that is a genuine difference in cost structure and is worth taking seriously. If it is cheaper because four of the rows are blank, it is not cheaper.

Adjacent deliverables to price at the same time

Two items are much cheaper when quoted alongside the walkthrough than after it. Layout communication is best handled by 3D floor plans, produced from the same drawings. And if any part of your audience will be evaluating the property remotely and at their own pace, an immersive version built on the walkthrough model is worth pricing while the model is still open. See virtual reality for where that is commercially justified.

Neither is mandatory. Both are significantly more expensive as a separate project six weeks later.

Who owns the files afterwards

The clause most often skipped is the one about the source scene, not the video. Almost every package delivers the rendered output. Far fewer transfer the project file, the material library and the camera setup, and those are what determine whether next year's update is a small edit or a rebuild. If your building will be marketed for more than one season, or if the unit mix or finish palette is likely to change, the right question at quoting time is what it costs to update the walkthrough in twelve months, not what it costs to own the file today.

The second clause worth reading is usage. Some quotes license the output for the developer's own marketing only, which becomes a problem the moment a brokerage, a listing portal or a hotel operator wants to run it. Neither of these points is unusual or adversarial. They are simply cheaper to settle before production than after, and a studio that answers both clearly is telling you something useful about how it works.

Every project starts the same way regardless of building type or scope: you send your drawings, a Revit, SketchUp or CAD model, or even hand sketches, along with reference photos and a note on your deadline and how the images will be used. There is no need to schedule a call before getting a number. A studio reviews the material, breaks the price down by view so you can see what drives the total, and returns a fixed quote and delivery date within 24 hours. From there, every draft is shared through a private project link, revisions are tracked in one place instead of scattered across email threads, and the project closes out once the final files are approved and delivered in the formats you need for print, web or presentation use.

Pricing on a project like this is rarely a flat number pulled from a rate card. Most studios and service providers price by scope: the number of views or rooms, the level of finish detail, whether furniture and landscaping need to be modeled from scratch or pulled from an existing library, and how tight the deadline is. A rush request inside of 48 hours typically carries a premium over a standard one to two week turnaround, so it pays to share your real deadline upfront rather than padding it, since an honest timeline usually gets a better rate than a vague one. Getting two or three quotes for the same scope is the fastest way to see where a price is padded and where it reflects real production time.

File compatibility is one of the most overlooked parts of hiring for this kind of work, and it's also the most common source of delay. Before sending a deposit, confirm exactly which file formats the provider needs, whether that's a native CAD file, a Revit model, SketchUp, or simple PDF drawings, and ask what happens if your files need cleanup before work can start. Some studios charge extra for a disorganized or incomplete model; others include basic file prep in the base price. Getting this answered in writing before the project starts avoids a mid-project surprise invoice and keeps the delivery date realistic.

Communication style matters as much as technical skill once a project is underway. Ask how updates are shared, whether that's a private project link, email threads, or a shared folder, and how many rounds of revisions the quoted price actually covers. Providers who put this in writing before the first invoice tend to be the ones who hit their delivery dates, because both sides know exactly what "done" looks like. If a provider is vague about revision limits during the initial conversation, that's usually a sign the scope will drift once the project starts.

Reviews and past client references tell a more reliable story than a polished portfolio page alone, since anyone can showcase their best five projects while quietly leaving out the ones that ran late or over budget. Asking for two or three references from projects similar in scale to yours, and actually calling them, remains one of the most effective ways to separate a provider who performs consistently from one who got lucky on a handful of showcase pieces. It takes an extra day, but it's a small cost against a project that could take weeks to complete.

Delivery formats are worth confirming before the final invoice, not after. A studio should be able to hand off high-resolution files for print, web-optimized versions for a listing or social post, and source files if your team plans to make small edits later without going back for a full revision. Ask whether these formats are included in the base price or billed as add-ons, since that distinction can shift the total cost more than the headline rate suggests.
