UInterchangeMeshBundleNode | Unreal Engine 5.8 Documentation

API > API/Plugins > API/Plugins/InterchangeNodes

This node represents a collection of UInterchangeMeshNode UIDs, each associated with N transforms.

This is used in the context of collapsing, where the transforms represent collapsed instances of the corresponding mesh nodes. The whole MeshBundle may be converted into a single static mesh or a single skeletal mesh. In both cases, the transforms are relative to the "collapsing root".

When the bundle has a valid SkeletonDependencyUid, it represents a group of skinned meshes that should be combined into a single skeletal mesh asset.
