created an key frame animation in Blender without bones but i don't know how to use it in Three.js.(i know to deal with bones)

Question

It's just a model to show the boneless animation. I want to know in which format to export because I'm unable to export this kind of animation in .json

Answer 1

Per three.js docs, I'd recommend using glTF-Blender-Exporter. It does support this type of animation. You can then load the result in THREE.GLTFLoader.
