WebGL surfaces with your own GLSL shader and Lottie animations; they keep running in the export

WebGL surfaces generate moving graphics, and you can enter custom GLSL code with a preview and error messages. Place Lottie files as animations with their aspect ratio. For an agency ad, add a moving background or prepared vector animation to the layout. Both follow the timeline and keep running in HTML and HTML5 ad output. In the PDF, Medusa rasterises the state at the playhead, producing a still image.

How to do it

1. Drag a Lottie JSON file onto the page.
2. Open «Timeline» with ⌥⌘T and check the animation with «Play».
3. In the timeline, choose «Export» › «Animated HTML …» for animated browser output.

Tips

• For PDF output, position the playhead at the still image you want before exporting.

Limits

The PDF contains a rasterised still image for WebGL and Lottie, without motion.
