"Rendering failed" Error in After Effects

No matter which composition I’m trying to render as Lottie in After Effects, I keep getting “Rendering Failed” right away.
Updated both LottieFiles & After Effects to latest versions.

Any idea what could be the issue?

Hi Neta,

would you be able to provide the .aep project file so I can take a closer look and help investigate the issue?

Thanks!

Hello @Neta,
Try removing any track mattes, merge paths, or raster images (PNG/JPEG) from your comp—Lottie doesn’t support them well and often fails rendering. Also, go to AE Preferences > Scripting & Expressions and enable “Allow scripts to write files and access network”. If it still fails, switch to Bodymovin for export and preview on LottieFiles.
