Help in Python Scripting to Import a Gltf Model

SHADOWxSTARK · June 13, 2021, 1:17am

Hey, experts
I am trying to import a GLTF model through python scripting in content browser in an specific folder but i am getting error every time i run the script

Python Script:

from os import path
import unreal

unreal.log("Creating Folder")
localfilePath=r"D:\Valorant_map_exporter\Test.gltf"
assetGamePath="/game/triad_art/"
assetName=path.splitext(path.basename(localfilePath))[0]
content_name="Light"
content_path=assetGamePath+content_name
#Content
unreal.EditorAssetLibrary.make_directory(content_path)
unreal.log(print(content_path))


task = unreal.AssetImportTask()
task.filename= localfilePath
task.destination_name=assetName
task.destination_path= assetGamePath
task.replace_existing = True
task.automated=True
task.save=True
#task.factory=unreal.DatasmithGLTFImportOptions()


task.options=unreal.GLTFImportFactory()
#task.options.Import_Uniform_Scale=100.0
#task.options.generate_lightmap_u_vs = False
#task.options.include_animation=True
#task.options.Lights=False
#task.options.Cameras=False
#task.options.Animation=False

unreal.AssetToolsHelpers.get_asset_tools().import_asset_tasks([task])
importedAssets = task.get_editor_property('imported_object_paths')
if not importedAssets:unreal.log_error('Failed to import {0}'.format(localfilePath))
else: unreal.log('Sucessfully Imported {0}'.format(localfilePath))

Error That I get :

Hello,

there are two plugins to import gltf: the gltf importer and Datasmith gltf importer. The datasmith one leverage the gltf importer and do some extra stuff on import. I believed they will be merged in the future.

Your approach looks good, and would rely on the gltf importer route. I am not sure why it is failing, I did repro on my machine. When I tried to force the factory it also failed with a different message.

What I managed to do and I can propose to you is to go the datasmith route:

from os import path
import unreal

unreal.log("Creating Folder")
localfilePath=r"D:\Valorant_map_exporter\Test.gltf"
assetGamePath="/game/triad_art/"
assetName=path.splitext(path.basename(localfilePath))[0]
content_name="Light"
content_path=assetGamePath+content_name
#Content
unreal.EditorAssetLibrary.make_directory(content_path)
unreal.log(print(content_path))
 
datasmith_scene = unreal.DatasmithSceneElement.construct_datasmith_scene_from_file(localfilePath)
 
# set import options
import_options = datasmith_scene.get_options()
import_options.base_options.scene_handling = unreal.DatasmithImportScene.CURRENT_LEVEL
 
 
result = datasmith_scene.import_scene(assetGamePath)
 
print (result.import_succeed)

Thanks for this I had already switched to datasmith one , I have one more issue if you can help me I wanna import a mesh from the content browser to the current level how I can do that with python?

UE_FlavienP · June 29, 2021, 9:03am

Basically you just have to do:

path_asset_in_content_browser = "/game/..."
loaded_asset = unreal.EditorAssetLibrary.load_asset(path_asset_in_content_browser)
spawn_location = unreal.Vector()
spawn_orientation = unreal.Rotator()
unreal.EditorLevelLibrary.spawn_actor_from_object(loaded_asset, spawn_location, spawn_orientation)

You can find some other samples here GitHub - ue4plugins/PythonSamples
