Export FBX 7.5 for DCC and real-time tools

Choose an FBX consumer profile, scene structure, origin, instances and appearance, then validate the static scene in its destination.

Choose the receiving profile

  • Use Binary FBX 7.5 for the normal compact interchange path; choose ASCII only when a receiving or diagnostic requirement needs readable records.
  • Select General DCC, Blender, Unity or Unreal according to the actual downstream application.
  • Use the profile as a tested baseline, then change units, axes, origin or structure only when the destination project requires it.

Structure, origin and instances

Decision table
DecisionChooseEffect
StructureSource model, element or mergedMore merging reduces nodes but sacrifices element selection and property granularity.
OriginFederation center, Preserve world or Explicit coordinateSmaller coordinates improve downstream float behavior; preserve world only when required.
InstancesPreserve or expandPreserving can reduce file size when the receiver handles shared geometry correctly.
AppearanceOriginal or Persistent overridesPersistent live overrides require Standard Export; Fast reads saved appearance.

FBX feature limitations

  • FBX v1 writes triangle meshes only; curves and points are not exported.
  • A receiver can reinterpret axes, units, pivots or material transparency; verify rather than assuming its profile defaults.
  • Merged structure cannot preserve the same per-element navigation as an element hierarchy.

Verify FBX interoperability

  1. Open in the exact consumer version

    Importer behavior changes by release and project template.

  2. Check axes, unit and origin

    Measure a known length and compare a control point or aligned source.

  3. Check hierarchy and selection

    Confirm the chosen structure exposes the objects the team needs.

  4. Check repeated geometry and appearance

    Inspect instances, normals, opacity and representative colors.

  5. Retain the report

    Record the consumer profile and any custom overrides with the delivered FBX.
