Resolved ECS physics simulation: graphics not updating / resetting after EOS

Hi,

I have the following setup in Unity2022.2.20 / Entities 1.0.8:
I created a sub scene and added a few 3d Cubes to it. I also attached a Rigidbody to each of them to make them follow gravity. There are two things I do not understand:

1) When I start the simulation, I can observe the cubes falling via their LocalToWorld values. However, the rendered cubes, do not move - they stay frozen in place. When I move such cubes via my own systems, the rendered cubes follow exactly their LocalToWorld position.
2) When I exit the simulation, now the cubes have been moved to the end point of the previous simulation, i.e I would have to manually place them back to where they were when I want to re-run the simulation.

Sorry, if these are super basic questions, I couldn't find answers via google.

 

Found the issue: I had to explicity install the physics package as well. That solved both issues.
