Re:Form is built on WebGPU — the modern graphics interface that lets a browser talk almost directly to your graphics card. That's what makes millions of triangles feel light. It also sets the requirements.

The short version

  • A desktop browser with WebGPU: current Chrome or Edge on Windows, macOS and Linux; current Firefox; Safari 26 on macOS.
  • A reasonably modern graphics card — anything from roughly the last decade that has working, up-to-date drivers. More video memory lets you push higher triangle counts comfortably.
  • A mouse is strongly recommended. Sculpting is a pressure-and-motion activity; a trackpad works, but a mouse (or a pen tablet that drives the cursor) feels far better.
  • Desktops, laptops and tablets with WebGPU — tablets get pen pressure, palm rejection and a touch layout (see Navigate the viewport). Phones aren't supported.

There is no download, no installer and no plugin. If the browser can run WebGPU, the full studio runs in a tab.

What happens without WebGPU

Re:Form is a WebGPU app: every stroke, subdivision and render runs on your graphics card. If your browser can't provide WebGPU, the studio doesn't open — you'll see a Re:Form needs WebGPU screen instead, listing the browsers that work.

On Chrome and Edge, WebGPU is on by default in current versions. If you see that screen on a machine that should support it, updating the browser and the graphics driver fixes it in most cases.

How hard can you push it?

The mesh lives in your graphics card's memory and stays there, so the ceiling depends on the card:

  • The Free plan caps subdivision at 4 million triangles — comfortable on mid-range cards.
  • Pro raises the ceiling to 80 million triangles, which wants a card with a healthy amount of video memory (8 GB and up is a good place to be). Past 50 million the app warns you first, because how well it runs depends on your card.

Whatever the plan, Re:Form only spends triangles when you ask it to — see subdivision and the triangle budget for how to place detail deliberately.
