I'm using the free version and not able to drag enemy into project. As for material I clicked on assets in the top and selected create. What suggestions do you have for this and further issues?
part 2. in your video after importing a package for vehicles-car, this does show up in hierarchy and project but not like in the video. I'm not able to drag and drop but need to either select car in the assets then right click on model and create. I do see the car without all items associated with it. Any short cuts ?
I'm not entirely sure what issue you're having. When you import the package it'll show up in the project panel. You can then drag the prefab (has a blue cube) into the scene or the hierarchy. If it doesn't allow you to drag it in, it's probably because you're selecting something different.
Free or Pro doesn't matter, it's the same process.
To create the prefab you can right click in the project panel and "create prefab" and drag your object from the hierarchy (or the scene) onto the empty prefab, or you can just drag it into the project panel.
Make sure you're dragging it from the hierarchy or the scene into the project panel.
