    """
    Summary: Verify that the change in a physmaterial library gets updated across levels

    Level Description: There are two levels that are being compared. Each are exact replicas with a shared
        material library
    modify_sphere - Starts between terrain and trigger with initial velocity in negative z direction and gravity disabled;
        has physx collider in sphere shape with material "to_delete", had physx rigid body, and sphere_shape
    delete_sphere - Starts between terrain and trigger with initial velocity in negative z direction and gravity disabled;
        has physx collider in sphere shape with material "to_modify", had physx rigid body, and sphere_shape
    terrain - Default terrain with transform inline; has physx terrain component
    trigger - Above the spheres, trigger is enabled; has physx collider in box shape with dimensions (5.0, 10.0, 0.25)
        and box shape with the same dimensions

    Expected Behavior: Materials deleted or modified have their changes update across levels. Initially the spheres will
        not bounce off the terrain after the change to the material library they will bounce up and hit the trigger

    Material Tests:
    Test 0 - Tests level 0 before the material change
    Test 1 - Tests level 1 before the material change
    Test 2 - Tests level 0 after the material change
    Test 3 - Tests level 1 after the material change

    Test 0 and 1 should be exactly the same. Test 2 and 3 should be exactly the same. Both modification to the material
    library should allow the spheres to bounce in Test 2 and 3. Therefore, both spheres will have a higher velocity and
    be able to trigger in Test 2 and 3 as compared to 0 and 1.

    Iterated Game Mode steps:
    1) Open the correct level for the test
    2) Open Game Mode
    3) Create and Verify Entities
    4) Wait for Sphere collision with Terrain Entity
    5) Wait for spheres to have a chance to hit trigger
    6) Modify Material Library
    7) Exit Game Mode

    Test Steps:
    1) Create Test Objects
    2) Run Game Mode steps once for each test
    3) Verify that spheres acted as expected
    4) Close Editor

    Note:
    - This test file must be called from the Open 3D Engine Editor command terminal
    - Any passed and failed tests are written to the Editor.log file.
            Parsing the file or running a log_monitor are required to observe the test results.
