Animation Render Stuck When Exporting with LottieFiles for AE Plugin

If your animation is stuck on rendering, it could be due to a few common issues. Here are some things you can check:

  1. Plugin version: Make sure to use the latest version of the LottieFiles for After Effects plugin. Check out the latest version of the plugin here. Using the latest version ensures compatibility with the latest features and bug fixes, potentially resolving rendering issues.

  2. File Size: Large file sizes can take longer to render. If your file is over 1MB, please allow a few minutes for the render to complete.

  3. Unsupported Features: Your animation might contain unsupported features that cause the render to fail. Check the list of supported and unsupported features on our supported features page.

  4. Track Mattes Issue: There is a known issue with Adobe After Effects and track mattes, which can prevent Lottie from rendering. To work around this issue, use the following steps:

    1. Use a track matte layer for each layer you want to matte.
    2. Keep the track matte layer on top of the layer you want to apply the matte to.

  5. Merge Paths: Ensure your composition does not include "Merge path". If it does, remove it from the composition before rendering.

  6. Adobe Illustrator (.ai) file: When using Adobe Illustrator (.ai) files, export them as compositions in After Effects and convert them into a vector-based format (convert into shape).

  7. PNG Sequence: If you are using a PNG sequence that is very large in size, it is advisable to optimize the PNG sequence for better performance during rendering.

  8. Nested composition: Check for any nested compositions within your main composition, as they might affect rendering performance. Flatten or pre-render nested compositions if possible.

  9. Character tool: Lottie animation files don't fully support third-party tools such as Duik, Limber, or Rubberhose. While it's possible to achieve the desired outcome with some workarounds, it may involve a bit of complexity and may not always be straightforward. A workaround that has shown promise involves baking the keyframes. This process entails converting expressions to keyframes on art layers and utilizing a script called Baked Parented Transform to bake any layer movement of parented layers. While this method may offer a solution, its effectiveness may vary depending on the complexity of the animation.
