Is a model required, or will drawings do?

Drawings work if they include plans, elevations, sections and reflected ceiling plans. A walkthrough shows ceilings, which a plan cannot describe, so an incomplete set forces assumptions that surface as corrections in review. A model in a common exchange format is faster where one exists.

How detailed does the shot list need to be?

A rough ordered list of spaces plus a note of the three moments the film is built around is enough. Without it the studio invents a structure, and the first review becomes a conversation about sequence rather than refinement, which consumes an entire revision round.

Why specify output formats before production?

Because aspect ratios are planned into framing rather than cropped from it. Adding a vertical or square version after delivery can require re framing every shot, which is close to a second edit rather than a simple export from the finished master.

When should music be decided?

Before the edit begins. The track sets the rhythm of the cut, so replacing it late means re cutting rather than swapping audio. Decide licensing at the same time, and request a music free version if the film will be shown in live presentations.

What to Give Your 3D Walkthrough Studio

Three dimensional walkthrough frame of an interior produced from a complete handoff package including drawings and finish schedule

Send the model or the full drawing set with the revision stated, a finish schedule or at least reference images per material, a shot list or storyboard, the output formats and aspect ratios you need, brand assets and any required disclaimers, music and pacing direction, the real deadline with what it serves, and the name of one approver. Walkthroughs have more variables than renderings, so an incomplete handoff costs proportionally more calendar time.

Everything here is information the studio will otherwise request one item at a time, with a day lost per exchange.

Model or drawings, with the revision stated

A model in a common exchange format is fastest. Full drawings work if they include plans, elevations, sections and reflected ceiling plans, since a walkthrough shows ceilings and a plan alone cannot describe them. State the revision in writing and notify the studio the moment a new set issues, because modeling from a superseded set is the one error that requires restarting rather than revising.

Model in FBX, OBJ, SKP, RVT or an agreed exchange format
Plans, elevations, sections and reflected ceiling plans if no model exists
Revision number and date in writing
Finish schedule, or two reference images per key material
Site context or an orientation note for correct sun position

A shot list beats a description

Even a rough list of the spaces to visit, in order, with a note of the three moments the film is built around, changes the outcome more than any other single input. Without it the studio invents a sequence, and the first review becomes a structural conversation rather than a refinement one, which costs a full round.

Say the output formats now

Wide for the website, vertical for social, a short cut for paid media, and whatever the sales office display requires. These are inexpensive when planned into the render and expensive afterwards, because a different aspect ratio can mean re framing every shot rather than cropping.

Brand, legal and disclaimers

Send logo files, brand colors, the typeface, and any disclaimer your legal team requires on marketing material. Adding a required disclaimer after final delivery means a re export at minimum and sometimes a re render if it affects framing. This is a small item that causes an outsized number of delays.

Music and pacing

Two or three reference films you like, with a sentence about what you like in each. Music licensing also needs deciding early, since the track affects the edit rhythm and swapping it late means re cutting. Say whether you need a version without music for presentations, which is more often than clients expect.

Name one approver and state the real date

Consolidated feedback from a single person avoids contradictory notes and the extra rounds they generate. Give the actual date and what it serves, since a broker tour, an investor meeting and a marketing launch have different tolerances for a rough cut, and the studio can often deliver a usable draft earlier if it knows what the draft is for. Detail expectations are covered in how much detail is needed.

Tell the studio what you do not have

Incomplete packages are normal and workable, but only when the gaps are stated. A studio that knows the finish schedule is still open can proceed on placeholder materials and swap them later at low cost, while a studio that assumes the schedule is final builds around it and has to rework. Say which items are missing, which are provisional and when the final versions arrive. That single paragraph in the handoff email prevents most of the mid production surprises that push delivery dates.
