I understand that Unity's default unit size is meters. But for some reason I want the default unit size to be in centimeters. There are no problems with modeling, animation, and particles because I can use centimeters as the standard. But there's a problem. If I change the scale of the object's size in centimeters, when I zoom in on it with the camera, the shadow becomes invisible. For example, if I set the scale of the basic 3D cube to 1, the shadow is visible from the camera, but if I set the scale of the cube to 100 or 1000 and zoom out so that it is all visible to the camera, the shadow is not visible. Is there any solution?
