Camera FBX importer example

[cghub-io]

Hi there,

just here an example of an working camera FBX importer for people to use as reference.

I have two questions though:

1. how can i pull in the focalLength from the fbx. Right now I am doing a workaround by exporting into a textfile from Maya

2. How to adjust the WorkingRange and ViewRange in the Sequencer. I have camera animations start at Frame 1001. Its a nightmare to adjust the viewing timeline to it each time.
   I found that the DataEditor is the variable which holds the property. But somehow I am not able to set it properly.

This here doesn't work.

from unreal_engine.structs import FloatRange, FloatRangeBound


# [u'ExpansionStates', u'ViewStart', u'ViewEnd', u'WorkStart', u'WorkEnd', u'WorkingRange', u'ViewRange']
seq.MovieScene.EditorData.WorkingRange = FloatRange(LowerBound=FloatRangeBound(Value=1001), UpperBound=FloatRangeBound(Value=1100))
seq.MovieScene.EditorData.ViewRange = FloatRange(LowerBound=FloatRangeBound(Value=1001), UpperBound=FloatRangeBound(Value=1100))
seq.sequencer_changed(True)

Cheers,

frame_start = 1001
frame_end = 1100
fps = 25
focal = 21
camera_fbx_name= 'C:/inf_010_v006_scale1.fbx'

tokens = camera_fbx_name.split('_')
# ['inf', '010', 'v006', 'scale1']


# Unreal stuff here
world = ue.get_editor_world()

exist = ue.find_asset('/Game/Cameras/{0}/{1}/{2}/{0}_{1}_{2}'.format(tokens[0],tokens[1],tokens[2]))

if exist:

    DialogException('Yo mate!\n\nCamera already exist in the scene.\n\n{0}_{1}_{2}'.format(tokens[0],tokens[1],tokens[2]))


else:
    factory = LevelSequenceFactoryNew()
    seq = factory.factory_create_new('/Game/Cameras/{0}/{1}/{2}/{0}_{1}_{2}'.format(tokens[0],tokens[1],tokens[2]))

    seq.MovieScene.FixedFrameInterval = 1.0/float(fps)
    seq.sequencer_changed(True)

    seq.sequencer_set_playback_range(float(frame_start)/float(fps), float(frame_end)/float(fps))
    cine_camera = world.actor_spawn(CineCameraActor)
    cine_camera.set_actor_label('{0}_{1}_{2}'.format(tokens[0],tokens[1],tokens[2]))

    # adjust focal length as sequencer_import_fbx_transform() doesn't do it. Maybe I am missing something..??
    cine_camera.CameraComponent.CurrentFocalLength = float(focal)
    cine_camera.CameraComponent.CurrentAperture = 21
    cine_camera.CameraComponent.post_edit_change()

    # add camera cut track (can be only one)
    camera_cut_track = seq.sequencer_add_camera_cut_track()
    seq.sequencer_changed(True)

    # add camera view
    camera = camera_cut_track.sequencer_track_add_section()
    camera_guid = seq.sequencer_add_actor(cine_camera)

    # # assign the two cameras to the camera cut sections (via binding id)
    camera.CameraBindingID = MovieSceneObjectBindingID( Guid=ue.string_to_guid( camera_guid ), Space=EMovieSceneObjectBindingSpace.Local )
    camera.sequencer_set_section_range(float(frame_start)/float(fps), float(frame_end)/float(fps))
    seq.sequencer_changed(True)

    # remove the Transform track as it pulls in fbx weirdly
    seq.sequencer_remove_track(seq.sequencer_possessable_tracks(camera_guid)[0])
    seq.sequencer_changed(True)

    # create new transform track and assign fbx to it
    transform_track = seq.sequencer_add_track(MovieScene3DTransformTrack, camera_guid)
    transform_section = transform_track.sequencer_track_add_section()

    # set frame range for playback
    transform_section.sequencer_set_section_range(float(frame_start)/float(fps), float(frame_end)/float(fps))
    transform_section.sequencer_import_fbx_transform(fbx_file, camera_fbx_name)

    # set frame rate of sequencer
    seq.MovieScene.DisplayRate.Numerator = float(fps)
    seq.sequencer_changed(True)

    seq.save_package()

Thank you so much for sharing this!

Hi, sequencer_set_view_range(start, end) and sequencer_set_working_range(start, end) have been added

Hi, sequencer_set_view_range(start, end) and sequencer_set_working_range(start, end) have been added

Thank you so much.
The sequencer_set_working_range(start, end) seems to work
but the sequencer_set_view_range(start, end) doesn't work. Bug?
