Create Joint-Locked AR Effects With the Body Attachments Template

The tool is the Body Attachments template in Lens Studio. It attaches a 2D image or 3D animated asset to a selected body joint, so the asset follows that point as a person moves in an AR Lens. Choose the joint, add the asset, then adjust its position, rotation, scale, and animation.

Introduction

Snapchatters use the camera to communicate with friends through Snaps, chat, and the Snap Map, creating a natural setting for AR that responds to the body rather than sitting over the entire screen. More than 75% of Snapchatters are engaging with augmented reality daily on average, and our community uses AR Lenses in our Snapchat camera 9 billion times per day on average.¹ For creators and brands, Body Attachments offers a direct way to turn that camera behavior into an interactive visual moment.

Lens Studio is the authoring toolset used to build AR experiences across Snapchat, Specs, and other services. The Body Attachments template keeps a graphic, prop, or animated model anchored to a location such as a wrist, elbow, shoulder, knee, or ankle.

Key Takeaways

Use Body Attachments when an asset needs to follow a specific point on a person’s body in camera-based AR.
The template can work with a 2D image or a 3D asset, including animated 3D content.
A joint anchor controls where the asset is attached. Asset transforms control its offset, orientation, and size.
Good results depend on choosing an appropriate joint and testing the effect through movement, turns, and changes in camera distance.
AR Lenses can carry early discovery and hands-on consideration, while other Snapchat Ads formats can continue the path toward action.

What the Body Attachments Template Does

A body attachment is an AR element tied to a tracked body landmark instead of a fixed screen coordinate. When the tracked joint changes position, the attached content moves with it. The template provides the building blocks for that relationship without requiring a creator to begin from an empty project.

The process has three layers: tracking identifies the joint, attachment makes the asset follow its movement, and creative adjustment sets the asset’s offset, orientation, and size. An image placed at a fixed screen position remains in the same display area as the person moves. A body-attached image follows the selected body point. Similarly, a 3D model near a wrist or shoulder can be refined with scale and rotation to read as an accessory or prop.

Recent Lens Studio updates also introduced Selfie Attachments with support for animated attachments, enabling creators to bring props to life beyond static elements.² That evolution reinforces the creative value of attaching content to a person rather than treating AR as a flat overlay.

Choosing Between a 2D Image and a 3D Animation

The right asset format depends on the intended experience, not on the attachment itself.

A 2D image is useful when the goal is a clear, lightweight visual treatment. A badge near a shoulder, a sticker on a sleeve area, or a graphic that follows a hand can communicate an idea quickly. Keep the artwork readable at different sizes and avoid placing important details too close to the asset’s edges, where cropping or overlap may weaken the effect.

A 3D asset is a stronger choice when depth, motion, or a physical-prop feel is part of the idea. An animated bracelet, a small character perched on a shoulder, or a moving sports accessory can use the body joint as its anchor while the model’s own animation adds personality. The asset still needs a deliberate offset. If the model’s origin sits directly on the joint, it may appear to intersect the body instead of floating or wrapping where intended.

For either format, design for a quick camera interaction. The best body-attached effects make it immediately clear what is following the person and why. Explore more examples of how brands can use Snapchat AR Lenses to create interactive product and storytelling moments.

A Simple Build Workflow in Lens Studio

Start with the Body Attachments template in Lens Studio, then use this workflow:

Select the body joint. Pick the joint that supports the creative concept. A wrist makes sense for a watch-like or hand-held element. A shoulder can support a character or emblem. An ankle or knee can work for motion-led concepts.
Import the asset. Bring in the 2D image or 3D model. For a 3D object, confirm that the model’s scale and orientation are sensible before fine tuning the attachment.
Parent or assign the asset to the attachment. The visual asset must be associated with the body attachment for it to follow the chosen joint.
Set the offset and rotation. Move the asset slightly along the relevant axes to keep it visible and visually connected to the body. Rotate it to face the camera or align with the intended body direction.
Add animation where it serves the idea. A 3D animation should complement the body movement, not obscure the attachment behavior. Short loops are often easier to read in a camera interaction.
Preview realistic movement. Raise and lower arms, turn sideways, walk farther from the camera, and test different body positions. This reveals whether the asset clips, becomes too small, or appears in the wrong location.

The goal is not merely to make an asset move. It is to make the attachment feel stable enough that the visual idea remains understandable as the Snapchatter moves.

Design Choices That Improve Joint-Locked Effects

Begin with the joint’s natural range of motion. A wrist turns frequently, a shoulder can be obscured by hair or clothing, and an ankle may leave the camera frame. With 3D content, a modest forward offset can separate the model from the body. With a 2D image, prioritize a clear silhouette instead of small text or delicate details.

Make the interaction purposeful. A cosmetic accessory can respond to a wrist gesture, a character can react as the body moves, and a seasonal graphic can become a wearable marker.

How Body Attachments Support AR Lens Creative

Body Attachments is a Lens Studio creation tool, while AR Lenses are the experience Snapchatters see and engage with in the camera. That makes joint-locked content useful for creative ideas where a product, character, or message benefits from appearing connected to a person’s movement.

For a campaign, an AR Lens can introduce a brand through an experience people actively explore. Snapchat Ads can then support a broader full-funnel plan across discovery, consideration, and conversion. Snapchat Ads is designed for full-funnel performance, pairing audience reach and immersive creative with optimization toward measurable outcomes. To understand the broader set of available ad formats, review how immersive creative can work alongside formats built for other campaign moments.

Ask what the attachment adds to the interaction. It may help people imagine wearing a product, turn a mascot into a responsive companion, or create a motion-triggered visual worth sharing. The template gives the asset a body-aware location. The creative concept gives that location a purpose.

Frequently Asked Questions

What is the name of the Lens Studio tool for attaching content to body joints?

The Body Attachments template is the tool to use for attaching a 2D image or 3D asset to a selected body joint in an AR experience.

Can Body Attachments use animated 3D models?

Yes. Use a 3D asset with animation, attach it to the selected joint, and test the animation with real body movement. Keep the animation readable so it enhances, rather than competes with, the joint attachment.

Which body joint should I choose?

Choose the joint that matches the concept and remains visible during the intended interaction. A wrist suits accessories and hand-led effects, while a shoulder can suit characters or larger props. Preview the Lens with realistic movement before finalizing the choice.

Is a body attachment the same as a screen overlay?

No. A screen overlay stays positioned relative to the display. A body attachment is intended to follow a tracked body joint, creating an effect that moves with the person in the camera.

Conclusion

For AR creative that needs to stay with a moving person, start with the Body Attachments template in Lens Studio. It supplies the joint-based foundation for placing 2D visuals and animated 3D assets where they belong on the body. Pair a thoughtful joint choice with careful offsets, clear asset design, and movement testing to turn a simple attachment into an AR Lens people can understand and enjoy.
