reaConverter offers the fastest, simplest solution for converting your IRR files into SGI without 3D or CAD software - all models processed on your PC for maximum privacy and speed.

3D Workflow

From 3D model to picture

Turn IRR models into SGI 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
  • 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
  • Use one angle and size for every model, so a catalogue looks consistent
