    For every project, it's crucial to determine several things before the application ... iteration process when the models will need some more changes and refinements. ... which objects are modifying its transform properties, like position and rotation. ... Use occlusion culling or LOD techniques to limit rendered parts of the scene.

    Changing the scale of your project is very challenging: you may have to re-import sprites, models and to manually re-adjust the position of all the objects in your levels. That’s why is so important to get the scale right from the very beginning.
