What Files Are Needed for 3D Animation?

Before starting a 3D animation project, having the right files and information ready can make the production process faster and more efficient. However, many companies considering 3D animation are unsure about which files they need to provide or whether the materials they already have are sufficient.

A well-planned 3D animation preparation process can reduce modeling time, minimize revisions, and help the animation production move forward more smoothly.

So, what files are actually needed for 3D animation?

What Files Are Required for 3D Animation?

The required files can vary depending on the type of project. The materials needed for a product animation may be different from those required for an industrial machine, architectural project, or technical animation.

In general, the following files and information can be useful for a 3D animation project:

• 3D model files

• Technical drawings

• Product dimensions

• Product photographs

• Material and color information

• Logo and brand files

• Animation script

• Storyboard or scene sketches

• Reference images and videos

• Text, graphics, and other content to be used in the animation

Let's take a closer look at each of these.

1. 3D Model Files

If you already have a 3D model, it can significantly simplify the beginning of the animation production process.

Depending on the project, commonly used 3D model formats include:

• FBX

• OBJ

• STEP

• IGES

• STL

• GLB / GLTF

• 3DS

• Blender files

• CAD files

However, the file format itself is not the only important factor. The model's geometry, level of detail, dimensions, topology, and material information can also affect the production process.

For example, a STEP or IGES CAD model can be extremely useful when creating an animation for an industrial product. A Blender, FBX, OBJ, or GLB model can often be prepared directly for animation after the necessary adjustments.

What if you don't have a 3D model?

Not having a 3D model does not mean that a 3D animation cannot be produced.

A 3D model can be created from product photographs, technical drawings, measurements, and reference images.

Therefore, not having an existing model is not necessarily a problem during 3D animation preparation.

2. Technical Drawings and Dimensions

Technical drawings are especially valuable for product, machinery, engineering, and industrial animation projects.

Useful information may include:

• Length

• Width

• Height

• Diameter

• Thickness

• Hole dimensions

• Component positions

• Assembly details

• Section views

Technical drawings can be provided in formats such as PDF, DWG, DXF, or other CAD formats.

If technical drawings are not available, accurate product measurements or dimensioned photographs can also help during the modeling process.

3. Product Photographs

Product photographs are particularly important when there is no existing 3D model.

If possible, photographs should show the product from multiple angles, including:

• Front

• Back

• Right

• Left

• Top

• Bottom

Close-up photographs of important details can also be useful for accurately recreating the product's geometry and surface characteristics.

The photographs do not necessarily have to be professional studio shots. Clear images that show the product's shape, materials, and details can provide a good starting point for 3D modeling.

4. Material and Color Information

Once the 3D model is created, materials play an important role in making the product look realistic.

For this reason, it is useful to provide information about the materials used in the actual product.

For example:

• Matte plastic

• Glossy plastic

• Brushed metal

• Stainless steel

• Glass

• Wood

• Fabric

• Leather

• Rubber

If available, color codes such as RAL, Pantone, HEX, or brand-specific color references should also be provided.

This information can have a significant impact on the final result, especially for 3D product animation projects where visual accuracy is important.

5. Logo and Brand Files

If your company logo or product branding will appear in the animation, vector files are preferred whenever possible.

Recommended formats include:

• AI

• EPS

• SVG

• PDF

PNG and JPG files can also be used, especially when they are high-resolution and have a transparent background.

Original logo files are particularly useful when the logo needs to be animated, applied to a 3D product, or displayed at the end of the video.

6. Animation Script

A 3D animation is not simply about making a 3D model move.

It is important to determine what will be shown, in what order, and what the viewer should understand from the animation.

For example, a product animation might follow this structure:

1. The product appears in a dark environment.

2. The camera moves around the product.

3. The product separates into individual components.

4. The internal mechanism is revealed.

5. The working principle of a specific component is demonstrated.

6. The product is assembled again.

7. The final frame displays the brand and product information.

Having a clear script before production helps keep the animation process organized and reduces unnecessary changes later.

If you do not have a finished script, the animation studio can also help develop the concept and scene structure.

7. Storyboard or Scene Sketches

A storyboard is a visual plan showing how the animation will look scene by scene.

A storyboard is not necessary for every project. However, it can be particularly useful for longer or more complex animations.

A storyboard can help define:

• Camera angles

• Scene order

• Product movements

• Graphics

• Transitions

• Close-up and wide shots

Planning these elements before production can reduce the number of changes required later.

8. Reference Images and Videos

Sharing examples of animations, camera movements, or visual styles that you like can help the production team understand your expectations more accurately.

For example, instead of simply saying:

“We want the product to rotate slowly.”

you can provide a reference video showing the exact type of movement you have in mind.

Useful references can include:

• Video links

• Images

• Competitor product videos

• Previous advertising videos

• Camera movement examples

• Lighting references

• Color references

• Visual style examples

Visual references can often communicate an idea much more effectively than a written description alone.

Can 3D Animation Be Created Without a 3D Model?

Yes.

Many companies interested in 3D animation do not have an existing 3D model. They may only have product photographs, technical drawings, or CAD files.

In such cases, the process may look like this:

References → 3D Modeling → Materials → Scene Setup → Animation → Rendering → Post-Production

Therefore, having no existing 3D model does not prevent you from starting a 3D animation project.

However, if 3D modeling needs to be created from scratch, this can affect the overall production time and cost.

Which File Formats Should You Send?

There is no single file format that is suitable for every 3D animation project.

File Type	Common Formats
3D Model	FBX, OBJ, STEP, IGES, STL, GLB, BLEND
Technical Drawing	DWG, DXF, PDF
Logo	AI, EPS, SVG, PDF
Photography	JPG, PNG, TIFF
Reference Video	MP4, MOV
Script / Text	PDF, DOCX, TXT

If your files are in different formats, you can still send them. Their suitability can be evaluated during the initial project review.

How Does 3D Animation Preparation Affect Project Time?

Preparing the necessary files before production can significantly improve the efficiency of the animation process.

For example, if you already have an accurate 3D model, technical drawings, and product photographs, less time may be required for modeling and reference research.

Similarly, defining the script and visual direction before production begins can reduce changes and revisions during the animation stage.

For projects with tight deadlines, 3D animation preparation can therefore play an important role in keeping the project on schedule.

3D Animation Preparation Checklist

Before sending your project to a 3D animation studio, you can use the following checklist:

•  Is a 3D model available?

•  Is the latest version of the model being provided?

•  Are technical drawings available?

•  Are the product dimensions known?

•  Are product photographs available from different angles?

•  Are material and color details available?

•  Are the original logo files available?

•  Are the features that need to be shown clearly defined?

•  Is an animation script available?

•  Is a storyboard required?

•  Are there reference videos or images?

•  Where will the final animation be used?

•  What resolution and video format are required?

Not all of these materials need to be ready from the beginning. In many cases, sharing whatever materials you already have is enough to determine what else may be needed.

Does Everything Have to Be Ready Before Starting a 3D Animation?

No.

You do not necessarily need to have every file prepared before starting a 3D animation project.

For example, if you only have product photographs, those images can be used to determine what additional information is required.

Likewise, if you only have a CAD file, it may be possible to prepare the model for animation and create the necessary materials and visual elements during production.

The most important thing is to clearly communicate the purpose of the animation, what you want to show, and what you expect the final video to achieve.
