Lets say I have a car, standard asset from unity asset store. I want to use it in my DOTS game with Physics. If I just attach convert entity to the prefab, does not seem to work (crash). I found some script that you create an empty game object, add the script, and then the prefab is entered into that script. That seemed to work but I can no longer see my car in scene view, which makes it hard to adjust the scene.
