Technical note

OFF to JXL: what carries over and what does not

A 3D model has no front of its own, so the JXL shows it from one viewpoint: the angles you set on the X, Y and Z axes, or a preset such as the isometric view. Whatever faces away from that viewpoint is not in the picture, so a part with features on several sides needs several images, which the multiple-frames option renders in one run. OFF describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the JXL afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

3D Workflow

From 3D model to picture

Turn OFF models into JXL previews without opening a 3D program. Set the angle once, and every model in the folder is rendered the same way.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
  • Keep unreleased designs and client models on your PC: nothing is uploaded
