Unreal in Phase 3 — Prop Prep

Blender builds the prop with its pivot at the gripUnreal imports it as a Static Mesh and attaches held props to the character's hand socket, so the prop rides the wrist with no offset.
Unreal's job in Phase 3

Import the prop, then let the socket do the placing. A prop arrives from Blender as a Static Mesh whose pivot is already the grip. Unreal's contribution is ordinary asset setup plus one key move: attach held props to the character's hand socket instead of hand-placing them. Aligned pivot + socket = the prop is correct in every pose, from every camera angle. The modeling side is on the Blender Phase 3 page.

What Unreal does in prop prep

3

Import the prop & attach it by socket · once per prop

Static props are dropped into the level; held props attach to the hand socket built back in Phase 2.

AImport as a Static Mesh

Use the FBX import workflow — the object origin you set at the grip in Blender comes in as the Static Mesh pivot. Verify it in the Static Mesh Editor.

BSet collision, LODs & materials

Assign simple collision, LODs where useful, and Material Instances — the same asset hygiene taught for any static mesh.

CAttach held props to the hand socket

In the shot, attach the prop (as a component or actor) to the character Skeletal Mesh's hand socket. Because the pivot is the grip, it lands in the hand with no offset — and follows the wrist through any pose.

DKeep props swappable

Socketed attachment means one hand can hold a sword this shot and a torch the next — no re-rigging, no re-animating. Static set-dressing props just get placed in the level.

If the prop floats, fix the pivot at source

A socketed prop that sits off the hand almost always means the Static Mesh pivot isn't at the grip — a Blender-side issue, not something to patch with a per-shot offset in Unreal (which breaks the moment the pose changes).

Fix: correct the object origin in Blender (Phase 3), re-export, re-import. Then attach-to-socket is exact everywhere.

Socket + pivot = the “floating sword” fix

The hand socket lives on the skeleton (Phase 2); the grip-pivot lives on the prop (Blender Phase 3). Get both right once and every shot just snaps — the exact fix called out on the pipeline page.

Where it goes next

Handing the prop on

  • Into the shot: props are snapped to sockets during Phase 5 — Shot assembly.
  • Rides the animation: a socketed prop follows every pose from Phase 4 automatically — you never keyframe the prop.
