Place 3D objects in the scene
In such cases uses a simple “blank” characters, which is not much load the computer polygons (that’s what each object is made of and it happens so that the final character consists of a few million such pieces, and this is very much even for modern powerful computers and therefore a simplified model of a few hundred polygons), and then replacing highly polygonal objects in their place.
At this stage, the director corrects camera movements, depth of field, object placement, and character clothing. When this phase is complete, these materials are passed to the modelers, who create more detailed objects in the scene.
