I used photoshop files to animate in after effects and I want to export them as a JSON file with lottiefile extension. But I can't export animations made with puppet tool. When I export it only export other animations except animation made with puppet pin tool. Is there any way to export puppet animation as JSON file? Because ,I want to use them in website.
That's simply not possible, because they are not transform operations, but actual pixel operartions. You may want to read the Lottie help on what is actually supported. Of course you can enable the "render unsupported features" option, but that a) may not work and b) only gives you embedded pixel data in you files, making them pretty much useless for serious web usage as intended.
