MeshExporter Documentation / Using the OBJ in Unreal

Using the OBJ in Unreal

The two common uses are MetaHuman conforming and morph targets. Both rely on unchanged topology.

MetaHuman Conform Workflow

1. Drag the edited OBJ into the Content Browser.
2. Import it as a Static Mesh.
3. Enable Combine Meshes when importing a full OBJ.
4. Use the imported Static Mesh in your MetaHuman conform workflow.

If conforming rejects the mesh, compare it with the original export. A changed vertex count, face count, or vertex order is the usual cause.

Morph Target Workflow

1. Open the matching skeletal mesh in Unreal Editor.
2. Open its Morph Target tools.
3. Choose Import Morph Target.
4. Select the edited OBJ.
5. Give the morph target a clear name and test it at a low value first.

Use an OBJ exported from the same character and matching LOD. Do not use a region-only file where the workflow expects the complete mesh.

Before You Import

Check that:

• Blender’s OBJ export Forward Axis was set to Y.
• Only the shape changed.
• The vertex and face counts match the original OBJ.
• The vertex order has not changed.
• The OBJ came from the same MetaHuman and LOD.
