Use automatic retopology tools in 3D software (like Blender’s Remesh or ZBrush’s ZRemesher) to generate a low poly mesh from a high poly model, then export it—no manual retopology required.
These tools analyze high poly details and create a simplified, topology-efficient mesh, ideal for games, AR, or VR.
For Blender users, try the Decimate modifier for quick reduction or Remesh with Simplify settings. For more control, use ZRemesher with a target polygon count before exporting as FBX or OBJ.
