Overview

Show Parent visualizes parent relationships in Blender by drawing arrows: yellow for object → parent and blue for bone → parent. Optional camera‑facing start markers (billboard circles) with adjustable size and colors help identify arrow origins.

🚀 Installation & Enabling

1. Install the addon via Blender: Edit > Preferences > Add-ons > Install and select the add‑on folder or copy into Blender add-ons directory.
2. Enable Show Parent in Edit > Preferences > Add-ons.
3. Open: View3D → Sidebar → Tool → Show Parent. Toggle Enable Parent Visualization.

Note: The add-on registers scene properties on enable; disable to remove them.

🧭 UI & Options

• Enable Parent Visualization — master on/off switch. ✅
• Only Selected — show arrows only for selected objects / bones.
• Show Start Point — show camera‑facing circle at arrow start.
• Start Point Size — radius of circle (Blender units).
• Objects / Bones Color — RGB pickers for arrow colors.

All settings are in the Show Parent panel; they persist with the blend file.

📐 Behavior & Modes

• Objects: arrows from object origin to parent origin (visible objects only).
• Bones:
  • Edit mode: uses Armature.data.edit_bones.
  • Pose mode: uses Armature.pose.bones (when Only Selected is active, selected pose bones use bpy.context.selected_pose_bones).
  • Object mode: uses rest pose bones (selection inferred from selected pose bones if requested).
• Start markers are drawn as small filled circles in a plane facing the viewport (billboard) so they remain visible from any view.
