The 3D model Barrel is low-polygon and consists of three parts:The barrel base has 960 vertices.The oak board has 4,000 vertices.The metal fastening part consists of three pieces placed on the edges and one in the middle, totaling 1,152 vertices.The Barrel model features a unique (procedural) texture for wood and metal, created in the Shader Editor without the use of plugins or textures from various online markets.The model was rendered using Cycles with a maximum value of 2048 samples. The modifiers applied to the model are Bevel and Smooth by Angle. The version of Blender used to create the model is 4.3.2.Using the Kodama add-on, I tested it on a 3D model and achieved a score of 89.5%. I have 1 allowable and 1 critical error; the latter cannot be resolved as they relate to the material. The non-critical error is the stretching of coordinates in the UVMap. The critical error is an incorrect connection of links, but if I try to fix it, I will lose this amazing procedural material. Therefore, I decided not to redo it.
