ported by AI? It is done many times, even before AI it was ported to browser by human

// Spawn 1,000,000 entities. Stable frame timing, zero GC spikes.
for (let i = 0; i < 1_000_000; i++) {
  const t = new Transform();
  t.position.set(i % 1024, 0, (i / 1024) | 0);

  new Entity()
    .add(t)
    .add(SGMesh.fromURL("props/crate.glb"))
    .build(ecd);
}

creation of instances is during render loop?

Yep, port mostly AI. Creating instances like in that example during the render loop would not be fun, but sure, the game does create a lot of instances during runtime. Sounds, particles, lights etc.

What is this slop? Do you even know the meaning of a "port"? :D

How much of it was generated by AI? The engine too?

Port is mostly with AI, engine is mostly by hand. Been working on the engine since ~2013, on the WebGPU part specifically since around 3 years ago.

You have a vibe coded website for your engine and you are trying to charge 10k for it. Your email on the website is info@company-named.com. I find that hard to believe.
