Could you build this?

Partial A skeletal animation editor's UI, JSON export, and MCP server are vibe-codeable, and small runtimes are feasible. A production-grade editor with mesh deformation, weight painting, atlas packing, and multiple robust runtimes is a large engineering effort.

What it would actually take: The stack would be a desktop or web editor with a mesh and bone system, weight painting, and keyframe timeline, plus an atlas packer and export formats. Runtimes in JavaScript, Rust, and Godot would need correct interpolation and deformation math. The hard parts are deformation correctness and format compatibility, which call for graphics and animation engineering experience.
