| Primary Deliverable | Exterior still, interior still, aerial view, animation, 360° panorama, or interactive model | Number of views, camera positions, output format, resolution, aspect ratio, and intended use | List every deliverable in a numbered schedule attached to the agreement |
| Image Resolution | Web images commonly use approximately 1,920 × 1,080 pixels; print and large-format applications require higher resolution | Whether the quoted price covers final-resolution files or only previews | Specify pixel dimensions, file type, color profile, and compression requirements |
| Source Materials | CAD drawings, BIM models, plans, elevations, material schedules, site photographs, and design references | Accepted software versions, model cleanliness, missing information, and responsibility for corrections | Define the document issue date and treat later design changes as new inputs |
| Visual Style | Photorealistic, illustrative, minimalist, atmospheric, diagrammatic, or competition-style | Reference images, lighting mood, season, weather, landscaping density, people, vehicles, and furniture direction | Include a visual reference board and define which creative decisions require approval |
| Project Complexity | Low: simple massing; medium: furnished or landscaped scenes; high: detailed materials, crowds, complex lighting, or animation | Geometry detail, custom modeling, entourage requirements, number of materials, and environmental context | Use a scope matrix separating included modeling from optional custom work |
| Turnaround Time | A single still often requires several business days; animation and multiple views generally require substantially longer schedules | Whether timing begins after receipt of complete files and whether review time is included | Set milestone dates for briefing, draft, comments, revision, and final delivery |
| Review Stages | Brief confirmation, clay or massing preview, materials and lighting preview, then final rendering | Preview quality, annotation method, response time, and who has final approval authority | Require written approval at each stage before progressing |
| Revision Allowance | A defined number of revision rounds is more predictable than unlimited revisions | What counts as a minor correction, major change, additional view, or new design direction | State the included rounds and provide an hourly or per-change rate for extras |
| Pricing Structure | Per image, per animation minute, per panorama, fixed project fee, or time-based billing | Included services, taxes, asset purchases, rush fees, rendering costs, and post-production limits | Request an itemized quotation with assumptions, exclusions, and payment milestones |
| Communication | Email, scheduled video meetings, shared review platform, or annotated PDF/image feedback | Time-zone coverage, primary contact, response target, file-sharing method, and meeting frequency | Nominate one decision-maker and consolidate feedback into one written response |
| Ownership and Usage Rights | Usage may cover marketing, planning submissions, presentations, competitions, websites, or social media | Who owns the source scene, custom models, textures, final images, and future-edit rights | Define license scope, territory, duration, portfolio permission, and confidentiality requirements |
| Quality Control | Checks should cover geometry, materials, lighting, composition, image artifacts, spelling, and file integrity | Correction period after delivery and procedure for reporting technical defects | Allow a defined post-delivery correction window for errors against the approved brief |
| Change Control | Design changes after approval can affect cost, schedule, camera composition, modeling, and rendering time | Approval process, written variation quotation, schedule impact, and authorization threshold | No out-of-scope work begins without written approval of the variation |
