Thanks for your reply. As you mentioned above, I forcely use FBXImporter, like this
import_data = unreal.FbxStaticMeshImportData()
import_data.combine_meshes = True
import_data.import_uniform_scale = 100
import_data.auto_generate_collision = False
import_options = unreal.FbxImportUI()
import_options.static_mesh_import_data = import_data
But the file extension is .obj, so the import task use Interchange framework, the parameter options doesn’t work.
I appreciate that you supply a useful snippet for me. I found unreal.ImportAssetParameters only supports a few parameter. what if I want to control the destination_name,combine_meshes,uniform scale, etc, and whether to import materials, textures or not.
