45 ACP aka 45 Auto Bullet Cartridge 3D model

This is a dimensionally accurate, photorealistic model of a .45 ACP / .45 Auto bullet cartridge that includes both an unfired cartridge and the components after firing. The detail in the model extends only to surfaces that can be seen externally after manufacturing or after firing, though the unfired projectile and unloaded cartridge (with primer installed) can be used as standalone assets, too.

The fired components include both the spent casing with a dented primer and the projectile with rifling marks for visualizing the bullet in flight. Each cartridge includes 3 separate components: copper-jacketed bullet, brass casing, and primer. At higher subdivision levels, these models can be used for photorealistic renders in even extremely tight shots.

Originally modeled and textured in Blender 4.3. Materials have been baked into PBR image textures for portability with different software packages.

Model:

--100% quads

--Real-world size (from engineering specification)

--2 variants (fired and unfired)

--3 separate objects per variant (casing, primer, bullet)

--Unwrapped UVs

--Subdivisions modifiable in Blender file

--3 formats (Blender, FBX, OBJ)

Note: The rendered product images show you what you get and are rendered straight from Cycles in Blender with no lens distortions, compositing, or touch-ups.

Textures:

--PBR workflow, fired cartridge includes metalness maps

--Casing is 4K, Primer and Bullet are 2K PNG textures

Note about subdivisions: Listed polygon and vertex count is for the unfired base geometry in Blender. It is recommended to use at least 2 subdivision levels (17,115 vertices / 17,088 faces) for visual fidelity and dimensional accuracy. You will get a noticeable improvement in tight shots for going up to 4 subdivisions (273,507 vertices / 273,408 faces), but any higher than that and the visual quality will be limited by the textures. FBX and OBJ exports have been made with 3 subdivisions.

Note about OBJ and FBX files: Some softwares may import materials with sRGB encodings for all the textures. Only the diffuse map should be applied with sRGB color space. You may need to manually change the encoding to 'non-color' (Blender) or its equivalent to get photorealistic results when using the FBX or OBJ files.
