The viewer and Space render real 3D in the browser with WebGL. A current Chrome, Edge, Safari or Firefox on a desktop or laptop is the target; phones can open the feed and the viewer, but Space is built for a mouse.
  • Hardware acceleration must be on. It is by default; if models render slowly or not at all, check your browser’s system settings.
  • Big models need memory. A Max clone can be a 50 MB file with a million triangles. Close other heavy tabs if the viewer stalls.
  • Ad blockers occasionally block the model download. If a viewer stays empty, try the page once with the blocker off.
  • Sign-in uses a Google pop-up. Allow pop-ups for unrealizex.com if the button does nothing.
The I key in Space shows a stats overlay with the frame rate and triangle count, which tells you quickly whether the model or the machine is the bottleneck.
