3D Workflow

From 3D model to picture

Turn HMB models into CG4 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
