A. Project Overview
"Metal Fear" is one of my favorite projects. It draws inspiration from industrial design and concept art aesthetics found in the Metal Gear IP. This project focuses on modeling hard surface models with distinct shapes and imbuing these models with a fearsome appearance through specific design elements. Technically, this project is a successor to the "Mech Warrior" project. All models and renders featured in this project were created using the free 3D voxel graphics software MagicaVoxel by Ephtracy. Post-processing was done with Photoshop.
How to read this page?
- Start with the design rationale before looking at the vehicle gallery.
- Read the geometrical logic and post-processing notes as part of the concept workflow.
- Treat each vehicle as a variation of recurring system clusters, not as an isolated design.
B. Preamble
The machines in Metal Fear are characterized by defined geometrical shapes, resembling the technical structures of heavyweight vehicles such as cranes, bulldozers, tanks, and other armored machines. These structures are designed according to the principle of "form follows function." The primary purpose of these machines is to be physically robust, easy to manufacture, and easy to maintain. Consequently, their geometrical shapes are technically crude and robust, rather than organic. Another limiting factor in their design is the production scale. Unlike consumer electronics or cars, these heavyweight machines are manufactured in smaller lots, necessitating standardized geometrical clusters and features in their structural design. A distinctive design aspect of Metal Fear vehicles is their incorporation of anatomical features found in life forms like spiders, crabs, snakes, etc. For example, adopting extremities from spiders makes the concept design more intimidating.
The core idea is not biomechanical realism, but the selective borrowing of threatening anatomical cues and translating them into manufacturable industrial forms.
C. Geometrical Representation
MagicaVoxel offers an efficient method for creating "hard surfaces" using voxels, as opposed to the more expensive 3D CAD or less precise 3D polygon modeling software. Hard surfaces with defined bevels, transitions, and undercuts can be modeled with voxels, utilizing "marching cubes" shapes during rendering. Another advantage of using the "marching cubes" representation is that these concepts appear super sharp and credible. Generating complex models with cool designs is time-consuming. To manage this complexity, I decompose the overall architecture of the model into logical elements, like found in systems engineering methodologies. From a professional perspective, we refer to this as "Modularity". In the 3D modeling community a familiar approach exists which is also known as "kitbashing".
Modularity
In industrial design, modularity is a key engineering technique that enables the creation of complex systems from smaller, independent subsystems, demonstrating versatility across various fields. In graphic design, particularly in the 8-bit and 16-bit video game era, modularity was exemplified through pixel graphic tiles, which were used as fundamental elements to construct intricate visual landscapes. This approach not only addressed technical limitations of the time but also fostered innovation and creativity, significantly impacting the gaming industry and beyond.
Voxel vs. Marching Cubes render mode - ボクセル対マーチングキューブレンダーモード
In a figurative sense, this means I divide the geometrical body of a Metal Fear vehicle into the following logical subsystems:
System Breakdown
- drive & joints,
- cockpit & control,
- armament,
- cooling & ventilation etc.
If I do that, I end up with a nice collection of logical elements that can serve as a basis for different vehicle platforms.
Decomposition of system architecture (kitbashing) - システムアーキテクチャの分解(キットバッシング)
Vehicle concept design by assembling systems - システムの組み立てによる車両のコンセプトデザイン
During my 1st modelling approaches in MagicaVoxel - which began in mid 2019 - my mechanical models models become more styled. Between the evolution steps I added details and made the concept designs more asymmetric. In my opinion "Asymmetry" is a very important factor in industrial design and beyond.
Asymmetry
Asymmetry is the violation of symmetry. Asymmetry is an important characteristic in biological organisms. Benefits of asymmetry sometimes have to do with improved spatial arrangements. From industrial design perspective the division of functionality between right and left may be beneficial too. In terms of efficiency and costs redundant components can be substituted and may lead to asymmetreical design. Deliberate usage of asymmetry can make a product design more interesting, less monotonous and more useful especially in terms of enhancing the user experience.
Design Rules
1 Break large vehicles into reusable structural clusters.
2 Favor legible silhouettes over ornamental detail.
3 Let subsystem placement communicate function.
4 Standardization creates credibility in small-batch military hardware.
5 Kitbashing is most effective when the design language remains consistent.
6 Use assymetry to make the design more interesting and unique.
D. Concept Art Aesthetics
Yoji Shinkawa, the lead character and mech designer for the Metal Gear series, introduced a striking art style technique. His art is renowned for its rough sketches, crisp outlines, and the use of watercolor effects. Additionally, he employs cinematic poses and perspectives to effectively stage his characters and objects. Applying perspective views is straightforward in 3D rendering. However, the final 3D render outcomes can sometimes appear too sterile or even unspectacular. Therefore, some post-processing in conventional 2D software is necessary to make the concept design stand out.
Filter-generated outline drawing effect - フィルター生成のアウトライン描画効果
You have two options here. If you have the skills, you can do the job manually, which results in a more natural look but takes considerably more time. Alternatively, if your skills are lacking, you're short on time, or you simply prefer an easier route, you can opt to use filters. Modern 2D bitmap software comes equipped with the right tools to assist you in this process. For instance, in Adobe Photoshop, ...
Workflow
- copy the layer with your rendered image,
- apply "find edges" filter on the copy,
- reduce saturation of that layer and,
- blend this layer via "multiplication".
Besides generating outlines, you can also create some dirty shading with grain. Add a camouflage texture while blending it with a "cloud" filter. Give the image more final touches using "charcoal," "tone separation," and "tone threshold" filters. This approach will give your render a dirtier, grunge look and make it appear less sterile. However, to achieve an outcome comparable to Yoji Shinkawa's work, you need to possess the skills and perform the entire post-processing manually by hand. Nonetheless, this effect seems promising and can serve as a good baseline for further experiments.

Codename: Stalker [コードネーム:ストーカー]
The Stalker is an All-Terrain Armed Scout (AT-AS), a lightweight, bipedal moving apparatus designed for reconnaissance ground operations in challenging terrain. It is equipped with a Gatling gun mounted on a rotating joint beneath the control cockpit. Additionally, it carries a cartridge containing four ballistic nuclear missiles and several air-to-air missile cartridges. Over time, I have refined the concept design, improving the center of gravity and making minor rearrangements of the missile cartridges and the position of the Gatling gun. Besides the "Asymmetry" of the mounted parts, another design characteristic of this vehicle is its distinctive ventilation devices attached to the main structure, which emphasize the general "industrial design" look of the vehicles in the Metal Fear project. This concept was the first in the Metal Fear project. The final mixed media artwork is a combination of a photograph and a 3D render. The base is a photograph taken with an iPhone SE (1st Gen) using the ProCamera app, combined with a MagicaVoxel marching cubes render. Retouching and post-processing were done in Photoshop, SnapSeed, and Procreate.
