The Extensions Platform build is the export-only part of the workflow, described by the developer as the most stable. The full SVG import and Layer Transform Tool workflow is available from source.
Lottie Export handles the export step of a Grease Pencil to Lottie workflow in Blender. It writes Grease Pencil content as vector shape layers into three container options: plain Lottie JSON (.json), a dotLottie ZIP package (.lottie), or a Telegram sticker/emoji file (.tgs). Lottie is a JSON-based vector animation format that describes animations using shape layers, paths, fills, and keyframes rather than video frames.
The add-on supports multiple Grease Pencil objects in one composition with an optional selected-only export, camera-based projection of 3D points to 2D composition pixels, and export of polyline and bezier path data per stroke. It exports fill and stroke styles including color, opacity, and stroke width, plus object and layer transform animation. Frame range and precision controls, an optional bake mode, per-stroke key reduction, and an optional export log file are included.
Some things are not supported: gradient fills and strokes, variable line thickness, images or image fills, GP modifiers including Line Art, and the GP effect stack. Only linear and ease keyframe types are supported and simplified; for more advanced easing, bake mode is available. The version on the Blender Extensions Platform is export only.
Lottie Export is best for blender artists exporting Grease Pencil animation to lightweight vector formats such as Lottie JSON, dotLottie, or Telegram stickers.
Lottie Export is completely free to download and use.
Lottie Export is compatible with Blender 5.1 and newer. You can install it directly from the Blender Extensions Platform by dragging and dropping into Blender, or download it and install from disk. The platform version includes export only (io_lottie_export), which the developer describes as the most stable part of the workflow. To install the full workflow with SVG import and the Layer Transform Tool alongside the exporter, you install from the developer's source repository instead. The extension does not require special permissions.
Lottie Export does not support gradient fills and strokes, variable line thickness, or images and image fills. It does not support modifier-evaluated Grease Pencil output, so the GP Line Art modifier and other GP modifiers and the effect stack are not exported, though you can bake and then export. It works on editable layer data rather than the final modifier stack output. Only linear and ease keyframe types are supported and simplified; for more advanced easing, use bake mode. There is no full Blender shading or render pipeline export.
Lottie Export is listed as free here and is released under the GNU General Public License v3.0 or later. It can be installed from the Blender Extensions Platform or built from the developer's source repository. For current licensing details and the full workflow, check the developer's page. The extension does not require special permissions when installed. A set of demo files is available from the developer to see the workflow in action.
Lottie Export uses camera-based projection to map 3D Grease Pencil points to 2D composition pixels. Because Lottie is a 2D format, perspective is approximated in the Lottie layer transform, and true 3D camera or parallax behavior is not fully representable. The add-on also notes that Lottie runtime differences may exist between players such as After Effects, lottie-web, and mobile runtimes, so results can vary depending on where the file is played back.
