AI-built Three.js game running hot on phones? Check pixel ratio. Agents often pass devicePixelRatio straight in, so a 3x screen renders 9x the pixels. Clamp it: renderer.setPixelRatio(Math.min(devicePixelRatio, 2)). More: shanebrumback.com/?v=2026102…

AI-built Three.js game freezing the first time a muzzle flash or explosion appears? That's shader compile. Have your agent add each effect to the scene at load and await renderer.compileAsync(scene, camera) before play starts. More: shanebrumback.com

My bullets were flying straight through bunker walls, with no hit and no impact. Here's how I made walls in my Three.js shooter actually stop shots and players: #threejs #gamedev shanebrumback.com/tutorials/…

If textures in your AI-built Three.js scene look washed out, check color space. When the agent loads maps with TextureLoader, set map.colorSpace = THREE.SRGBColorSpace on color and emissive maps only. Normal, roughness and metal maps stay linear. More: shanebrumback.com

If an AI agent spawns enemies from one rigged GLB, check it isn't using model.clone(). Skinned copies share bones and freeze or move together. Use SkeletonUtils.clone(gltf.scene) and give each copy its own AnimationMixer. My rigged soldier tutorial: shanebrumback.com/tutorials/…

Tip if an AI agent builds your Three.js sky: have it feed the sky into scene.environment with PMREMGenerator, so armor, water and metal reflect the same sky you see. Skip it and AI-built scenes look pasted together. My rigged soldier tutorial: shanebrumback.com/tutorials/…

When the steam engine first appeared in the late 1700s, many called it dangerous, unnecessary, and a threat to traditional work. The same pattern repeated with personal computers in the 1970s and 80s, when critics dismissed them as expensive toys that would never replace real tools or skilled labor. In both cases the early rejection came from people who measured the new technology only by what already existed. Time proved them wrong as the steam engine powered the industrial age and the PC reshaped nearly every field. New tools always face this kind of pushback before they become the standard.
