3D models are used for product images, games, animation, augmented reality, architecture and 3D printing. Each use needs a different kind of model, and a model built for one purpose often fails in another. A detailed product render model may be far too heavy for a mobile game, and a game model may not be accurate enough for manufacturing. This article explains what to decide and prepare before hiring a 3D artist so you get a model that fits its purpose.
1. Decide what the model is for
The single most important piece of information is the model's purpose. Common uses include:
- Still renders for marketing, catalogs and online stores, where realism matters most.
- Animation, where the model must move cleanly and may need a rig.
- Games and real-time apps, where performance limits the level of detail.
- Augmented reality and web viewers, where small file sizes are essential.
- 3D printing or manufacturing, where accuracy and solid geometry matter.
- Architecture and interiors, for visualizing spaces before they are built.
If you need the model for several purposes, say so. The artist may create a high-detail master and lighter versions for real-time use.
2. References and measurements
Provide as much reference as possible: photos from all sides, technical drawings, CAD files, sketches and exact measurements. For products, a physical sample helps the artist check proportions and materials. For characters, a character sheet with front, side and back views is ideal; our character design article explains how to prepare one. For buildings, floor plans, elevations and material lists are essential.
3. Level of detail
Decide how close the camera will get and how detailed the model must be. A product shown in close-up needs accurate small features, like buttons, seams and text. A background object in a game can be simple. Higher detail takes more time and produces heavier files. Describe the closest view you plan to show so the artist can balance quality and efficiency.
4. Materials and textures
Describe the materials: brushed metal, matte plastic, fabric, wood, glass or leather. Provide color codes and photos of finishes. If several color or material variations are needed, list them, because a well-prepared model can switch variations quickly. Ask what texturing approach will be used and whether textures will work in the software or engine you plan to use.
5. Technical requirements
For games, AR and web viewers, share technical limits such as polygon count, texture sizes and file size. Name the engine or platform the model will be used in. For animation, explain the movements needed and whether a rig is required. For 3D printing, specify the printer type, scale, minimum wall thickness and whether the model must be split into parts. For manufacturing, ask whether the artist can deliver engineering formats or whether a CAD specialist is needed.
6. File formats and delivery
List the formats you need, such as the native file from the artist's software, FBX or OBJ for exchange, GLB for web and AR, or STEP for engineering. Ask for organized files with named parts and materials, textures included, and a few preview renders. If you plan to create renders or animation later, ask for the scene setup with lighting and cameras too.
7. Process and feedback
Most 3D projects move through stages: a rough blockout to confirm shape and proportions, detailed modeling, then materials, lighting and final renders. Give feedback at each stage, especially the blockout, when changes are quick. Agree on revision rounds and how feedback will be shared, such as screenshots with notes.
8. Rights and reuse
3D models are valuable assets that can be reused for years. Agree on whether you receive full ownership or a license, whether the artist can sell the model elsewhere and whether you receive source files. If the model is based on your unreleased product, discuss confidentiality.
Preparation checklist
- Purpose and all planned uses.
- Photos, drawings, measurements or CAD files.
- Closest view and level of detail.
- Materials, colors and variations.
- Technical limits for engines, AR, animation or printing.
- File formats and delivery contents.
- Stages, revisions, rights and confidentiality agreed.

FAQ
What is polygon count?
The number of small surfaces that make up a model. Games and AR need low counts; still renders can use more.
Which file format should I ask for?
It depends on your software and use. Common formats include FBX, OBJ, GLB and STEP for engineering.
Can a 3D model be used for 3D printing?
Only if it is built as a closed, printable solid at the right scale. Say so in advance.
What are textures?
Images and material settings that give a model its color, surface detail and finish.
Do I own the 3D model?
Agree in writing on ownership or license, and ask for the source files.
