3D Workflow

From 3D model to picture

Turn AC3D models into AVIF 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

Twitch thumbnails keep saving as AVIF and my editing software freaks out. reaConverter swaps them to JPEG instantly. Now I can actually post my ‘🔥HOT TAKES🔥’ without crying over file errors.

Google Photos auto-saved my pics as AVIF files that won’t open anywhere. reaConverter rescued 3 years of memories AND kept the quality. Take that, ‘innovation’!
