Work in Progress (WIP) Lowpoly Model of the Amazon-Class Type 21 Frigate, as per its Typical '82 Configuration.
Store Page: https://artstn.co/m/k1K7q
Background & History:
The Amazon-Class Type 21 Frigate was a British Royal Navy General Purpose Frigate, designed in the late 1960s, built in the early '70s and served from the mid '70s to the early '90s, most notably during the Falklands War of 1982, providing the backbone of the British Naval Taskforce sent to recapture the islands. During the '90s, the remaining Type 21 were sold off to Pakistan, refitted with some new weapons & reclassed as the Tariq-Class Destroyer.
Except for HMS Amazon, all the class took part in the 1982 Falklands War as the 4th Frigate Squadron. They were heavily involved, performing extensive shore-bombardment missions and providing anti-submarine and anti-aircraft duties for the task force.

Model Info:
Firstly, this Frigate isn't just a single model, but rather a set of models with every primary Weapon & Sub-System being their own independent set of models & textures to maximise flexibility & optimisation. This not only means that this Frigate can be easily reconfigured, but also allows other ship types & platforms (such as the ITB Exocet Trailer) that share these same weapons & sub-systems can use them while sharing the same textures/materials, reducing client memory load & creating common draw calls.
I've based the model & textures on the standard configuration as per the 1982 Falklands conflict, with painted out markings & with 4x MM38 Exocet anti-ship missile, but not on any particular ship in the class.
Being primarily made for use on the Refractor 2 engine, I aimed to keep this model as low poly as possible while still trying to retain a high level of detail through highly optimised meshes, high poly normal map baking & texture detail.
This Frigate model is fully functional, with every Weapon & Sub-System able to move, rotate & fire as per its real-life counterpart.
Model Stats:
The Frigate, with all of its Weapons & Sub-Systems, comes to 61k Triangles / 34.8k Polygons / 38.3k Vertices(LOD0).
The Frigate itself, without any of the Independent Weapons, Sub-Systems & Props, comes to just under 38k Triangles / 21.3k Polygons / 25k Vertices.
For all the Weapons, Sub-Systems & Prop model LOD0 comes to 23k Triangles / 13.5k Polygons / 13.3 Vertices.
Textures for the Frigate's hull, superstructure & small details are on 4096 x 2048 px Diffuse, Specular & Normal Textures, with an additional 1024 x 512 px Diffuse, Specular, Normal & Opacity textures for all the transparent parts.
Textures for the independent Weapons & Sub-Systems are all on separate maps for maximum flexibility. But together, they have a pixel area of 27,033,600 px^2 at their maximum resolution. However, at the resolution I plan to use it ingame, where they have around the same texture detail level of the Frigate, they have a pixel area of 6,586,368 px^2, which is just under that of a 4096x2048 px texture.
Please keep in mind that these textures are still WIP; the Normal and Spec maps especially have a lot more work planned for them, & there is also the creation of missing PBR textures. Also, the Normal maps have their Green Channel inverted from what most engines use by default.
