The model comes with realistic PBR materials.
The 3D model is available in the following file formats:
-.blend (NATIVE)
-.fbx
-.obj
-.obj (Legacy)
-.mtl
-.stl
The textures required to render the model are also included in the package. They come in a separate zip file, and they are also already packed in the .blend file.
If you have any questions or specific requests, I will be always available to help.
