The models have been modeled in Blender 3.2, textured in Substance 3D Painter and rendered in Cycles. Both Crossbow and arrow are low poly, game-ready models. In the blender file, you will be able to find, low poly, mid-poly and high poly models of each model (Crossbow and Arrow). The sizes of both are taken from the real references and models as real sizes.
In textures, you will be able to find textures for all polygon types of models and also textures for Unity 3D.
Polygon and Vertex Sizes for each polygon type :
Low Poly Models : Crossbow : Polygon Size (Faces) : 1812 Vertices : 2114
Arrow : Polygon Size (Faces) : 339 Vertices : 389
Mid-Poly Models : Crossbow: Polygon Size (Faces) : 20874 Vertices : 22161
Arrow : Polygon Size (Faces) : 777 Vertices : 831
All other formats have been exported from Blender 3.2 and FBX files tested in FBX review of AutoDesk. In case of any problem in any file format or model or texture, please feel free to contact me.
