How to use Three.js and React Three Fiber in Next.js without SSR errors.
Three.js assumes a browser environment. Next.js renders on the server. Here's how to bridge the gap.
Mark the entire Three.js tree as a client component with "use client" at the top. The component won't render on the server at all.
Dynamic import when: you want code splitting and loading states.
"use client" when: the component is always needed and you want simpler code.
