3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not PMX files. reaConverter renders each model to FITS at the angle you set, a whole folder at a time.

  • 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
