The 57 MM Bofors MK3 Naval gun is designed by Bofors Defense which is currently owned and manufactured by BAE systems.

The United States have a slightly modified version, which is named the Mark 110 Mod 0 57mm gun.

This naval deck gun is used by various navies around the world;

Brunei (Darussalam)Canada (Halifax)Finland (Hamina)Malaysia (Gowind)Mexico (Sierra,Durango)Sweden (Visby)United States (Legend, Freedom, Independence)The model is created in 3ds Max 2015, and rendered in V-Ray 3.2. I work as close to real world scale as i can (in meters). I build my models based on references found on internet. Blueprints, photos and data found on internet.

The materials are V-ray materials without textures. I have built most of my models with the same multi-material setup for easy adjustment. Personally i like the clean untextured look, but if you are in the real-time game engine scene you will need to do some unwrapping work. For now, i will leave the models as they are.

For modelling i like to create hard surface models without sub-d options. I have subdivided the models before cutting out the doors or other shapes. My opinion is that this will keep polycount relatively low. The edges are bevelled in.

The shown renders are created with HDRI lighting, which is excluded from the scenes. The images are without Photoshop post processing, except cutting out the background an giving them a simple drop shadow.

The model is divided in Base, turret, and gun for easy positioning. The pivots and hierarchy are setup correctly.
