What to Include in a 3D Rendering RFP: A Brief That Gets Comparable Quotes

When quotes from three studios differ by a factor of five, it usually means they are quoting for three different jobs. The fault is almost always in the brief, not the studios.

A rendering RFP does not need to be long. It needs to be specific about seven things.

1. The deliverable count, precisely

Not "product images for our new range" but a number and a breakdown.

State how many products, how many images per product, and what each image is. For example: twelve products, seven images each, comprising one white-background packshot, one three-quarter hero, three detail views, one dimensional view and one contextual scene.

This single change does more to make quotes comparable than everything else combined.

2. Output specifications

• Pixel dimensions of the largest required output
• File formats needed, including whether transparent-background PNGs are required
• Aspect ratios, if you need multiple crops
• Colour profile, if you have a requirement, particularly for anything going to print

If any images will be printed at large format for trade shows or retail, say so here. It changes how the work is set up from the beginning.

3. What source material you can provide

Be honest about this. The most common cause of a quote being revised upward is source material turning out to be worse than described.

State clearly:

• Whether you have CAD, and in what format
• Whether the CAD is complete or partial
• What physical samples exist and whether they can be shipped or photographed
• What reference photography exists
• Dimensioned drawings, material specifications, colour references

If you have nothing but photographs of a competitor product, say that. A studio that quotes knowing the reality will quote correctly.

4. Materials and finishes

List every material and finish per product. This is where cost genuinely varies, because a matte plastic housing and a polished chrome one are not comparable amounts of work.

Flag anything difficult early: transparency, liquid, fabric, fine mesh, brushed or polished metal, iridescence, backlit elements.

5. Revision structure

Specify how many revision rounds you expect to be included and, more importantly, define what a revision is.

A useful distinction:

• Included revisions: adjustments within the agreed scope, colour, lighting, minor positioning
• Additional scope: new camera angles, new products, new environments, changes arising from a product redesign

Ask each studio to price against this definition. It prevents the most common commercial dispute in the category.

6. Ownership and file handover

State what you require, and require an explicit answer rather than silence:

• Do you receive the 3D model and scene files, or only rendered exports?
• What licence applies to the images? Perpetual, worldwide, all media, or limited?
• Can you commission a different studio to work from the delivered model later?
• How long will the studio retain the project files, and can you request re-renders?

Studios will price differently depending on the answer, which is correct and fair. What matters is that you compare like with like.

7. Timeline and dependencies

Give the real deadline and what it is tied to, a print run, a trade show, a marketplace launch. Studios plan differently for a hard external date than a soft internal one.

Also state your own review capacity honestly. If your approvals go through a regulatory reviewer with a five-day turnaround, that is part of the timeline and should be in the brief.

Optional but valuable

A reference set. Two or three images, from anywhere, that represent the look you want, with a note on what specifically you like about each. This is worth more than several paragraphs of description.

Your brand guidelines, if imagery must sit alongside existing photography without clashing.

The channels the images will appear in. Amazon, own site, retail partners, print, trade show. Each has requirements that are cheaper to design in than retrofit.

How to evaluate what comes back

Once quotes arrive, compare on:

• Whether they quoted the deliverable list you specified, or substituted their own
• What they excluded, which is usually more revealing than what they included
• Their answer on source files and licensing
• Whether their questions suggest they understood the product
• Total cost to usable assets, not headline price per image

A studio that comes back with three sharp questions before quoting is generally a better sign than one that returns a number the same day.
