The software used for this model is blender, which is a high-poly model. The carving part of the model has been optimized into a triangular surface model, and the remaining manual wiring and construction parts retain detail modifier information. The number of faces and vertices displayed by the model is the total count after subdivision of the model.The model has no UVs and no pixel maps. The rendering uses blender's procedural textures and materials. The renderer uses Cycles. The blender project file comes with a camera and lights.In order to meet possible 3D printing needs in the future, the models are all solid models with closed open surfaces (except for the eyeball reflective layer, and by the way, only the eyeballs have motion controllers that can adjust the line of sight).The crown part of the helmet can be removed and is made in two styles, which should be the Gallic style and the Italian style as I understand it.Model files are exported in Fbx and obj formats, Fbx is the model before subdivision, and obj is the model after subdivision.
