You can use the “play mode” build without installing Unity Editor, so it’s a good way to start exploring Isaac SDK and Isaac Sim Unity3D. On the other hand, the “editor mode” projects and packages, which require the Unity Editor, allow you to create your own simulation environment for Isaac SDK.Unity3D installation workflow
