3D Workflow

From 3D model to picture

Turn MD3 models into IFF 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
  • Use one angle and size for every model, so a catalogue looks consistent
  • Script the job from the command line for pipelines and scheduled runs
