3D Workflow

From 3D model to picture

Turn 3D models into ICO 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
  • 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
