A realistic model of a chocolate sponge cake. The scene file contains models of two pieces of cake in different positions, a napkin and a packaging box. For convenience, all materials are combined into a Multi/Sub-Object, and the corresponding Material IDs are assigned to the models, which allows you to use one Multi/Sub-Object material for any object in the scene. Texture names are logical and understandable. A library of materials has been added to the archive file.
