Exporting a spawnable through Python doesn't work

1. Create a level sequence with a spawnable (cube or skeletal, doesn't matter)
2. Export FBX

RESULT: Spawnable didn't exported because it doesn't exist at export time.

EXPECTED: The spawnable object gets exported to fbx and can be opened in Maya

 

 

Alternative repro:

1) Create a blueprint derived from actor

2) Add a skeletal mesh component and assign a skeletal mesh

3) Add actor to a level sequence and assign an animation to skeletal mesh component

4) run the following python script (with correct fbxFileName and levelSeqPath)

import unreal

1. get the fbx export file name
   fbxFileName = "C:/temp/ue_animation.fbx"

levelSeqPath = "/Game/Cinematics/Takes/2020-01-10/GE_0004_0001"

1. get the world
   world = unreal.EditorLevelLibrary.get_editor_world()

1. load the sequence
   sequence = unreal.load_asset(levelSeqPath)

1. get all the sequence bindings
   bindings = sequence.get_bindings()

1. list of Unreal class types that can go through this export process

1. set the export options
   exportFBXOptions = unreal.FbxExportOption()

exportFBXOptions.fbx_export_compatibility = unreal.FbxExportCompatibility.FBX_2018
exportFBXOptions.ascii = True
exportFBXOptions.vertex_color = True
exportFBXOptions.level_of_detail = True
exportFBXOptions.collision = True
exportFBXOptions.export_morph_targets = True
exportFBXOptions.export_preview_mesh = True
exportFBXOptions.map_skeletal_motion_to_root = True
exportFBXOptions.export_local_time = True

seqTools = unreal.SequencerTools()

seqTools.export_fbx(world, sequence, bindings, exportFBXOptions, fbxFileName)
5) FBX will not export properly

NOTE: if the actor is a skeletalMeshActor (or a child class of skeletalMeshActor) it will export properly
