editor_create_object

Generate and place new objects/actors in Unreal Engine with specified class, name, location, rotation, scale, and properties. Returns detailed actor data including final transform values.

Instructions

Create a new object/actor in the world

Example output: {'success': true, 'actor_name': 'StaticMeshActor_1', 'actor_label': 'MyCube', 'class': 'StaticMeshActor', 'location': {'x': 100.0, 'y': 200.0, 'z': 0.0}, 'rotation': {'pitch': 0.0, 'yaw': 45.0, 'roll': 0.0}, 'scale': {'x': 1.0, 'y': 1.0, 'z': 1.0}}

Returns created actor details with final transform values.

Input Schema

Name	Required	Description
`location`	No	World position coordinates
`object_class`	Yes	Unreal class name (e.g., 'StaticMeshActor', 'DirectionalLight')
`object_name`	Yes	Name/label for the created object
`properties`	No	Additional actor properties. For StaticMeshActor: use 'StaticMesh' for mesh path, 'Material' for single material path, or 'Materials' for array of material paths. Example: {"StaticMesh": "/Game/Meshes/Cube", "Material": "/Game/Materials/M_Basic"}
`rotation`	No	Rotation in degrees
`scale`	No	Scale multipliers
