It is built for performance from the first line of code. ToolBox3D is written in Rust, compiled to WebAssembly and drawn with WebGPU. Data is shared instead of copied, work is redone only when something actually changes, and long-running jobs are designed to run in the background so the editor stays responsive.
It is built around five connected editors. Each editor owns its part of an asset — geometry, rig, animation, textures — and hands its changes to the others through a shared cache when you switch, so work in one editor never silently overwrites another's.
And it is designed to be scriptable from top to bottom: every authoring action is a registered operation, so the interface, future scripting and AI-assisted automation will all go through the same path with the same rules and the same undo.
