FR-AI / ANALYSIS

Why it is worth attention

It solves a native Blender limitation: showing different silhouettes (front, side, top) in their respective orthographic views while keeping the viewport clean in perspective, all without scene objects or viewport fighting.

Who it is for

  • Character modelers needing scale reference
  • Game developers using Blender for asset creation
  • Technical artists wanting non-destructive viewport overlays
  • Blender users frustrated with image empties in perspective

Use cases

  • Placing a front silhouette in Front orthographic view and side silhouette in Right view simultaneously
  • Calibrating character scale against a known height from an active object
  • Overlaying concept art or turnarounds that only appear in the correct viewing angle
  • Game engine pipeline where forward axis (+X) differs from Blender's default (-Y)

Strengths

  • No scene objects: images are drawn directly into the viewport like the grid, keeping the outliner clean
  • Automatic height calibration from image alpha or background color, with fallback
  • Per-viewport drawing solves the multi-viewport fighting issue that native hide_viewport flags cause
  • Depth modes (behind/everything, front/everything, relative to active object) offer placement flexibility

Considerations

  • No viewport gizmo for interactive positioning – must use sidebar Origin field
  • Opaque background images render as translucent rectangles (no keying at draw time)
  • User-rotated orthographic views off the axis do not show images unless Tolerance is increased or Only Matching View is off
