@webloved: How I build with GPT-6 Astra 👇 Academy in bio 🔗 Full prompt goes in the Academy soon. Hours of building and breaking this one got it there. Five sections, five 3D worlds, one canvas. And I never prompted the sections. Ask a model for "a scroll site where each section has its own 3D scene" and it gives you five canvases, five renderers, five animation loops all running at once. Looks fine on the first screenshot, kills the laptop by section three. So the first message is the stage rule, before any of the art: "One renderer and one canvas for the whole page, fixed behind the content. Sections are scenes that get added and removed from that stage. Only the scene currently in view runs its update loop. When a scene leaves the viewport, stop its loop and dispose its geometries, materials and textures. Never more than one scene alive at a time." Then, and only then, I describe the worlds one by one. The model is now building inside a system instead of stacking demos. Same reason the fluid, the characters and the moon can coexist without the fan spinning up. Give it a stage before you give it a scene. Which section would you have opened on? Save this 🔥 #astra6 #webdesign #threejs #aiwebsites #frontend
