The idea behind this mechanical heart was to combine the look of industrial machinery with the form of a human heart. It represents the cold and oppressive nature of a city. Inside the heart, there are pipes, gears, and various mechanical parts. Each of these elements symbolizes the pressure and restrictions that the city places on individuals. This heart is not only the city’s power source but also a symbol of its emotionless and mechanical operation. The goal of the texturing process was to express this feeling of coldness and oppression visually.

To achieve an industrial look, I used dark gray and black as the base colors. The metal texture was created with a combination of shiny and rough areas. This contrast made the surface feel more realistic, showing how light reflects off polished parts while worn-out areas stay dull. Scratches, rust, and dirt were added to make the heart look aged and heavily used, as if it had been operating under pressure for a long time. These small details made the heart feel more grounded and believable as part of a tough industrial environment.

The glowing red parts of the heart added a sense of technology and life. The cracks and joints emitted a red light, representing the energy flowing through the heart. This also created a strong contrast with the dark base, making the heart look more striking. The glowing effect was made using an emissive texture, with a gradient that fades outward, giving the impression that energy is leaking from inside. The red glow not only emphasized the technological aspect but also added a cold and dangerous feeling, which fit well with the oppressive theme.

For the pipes and gears, I used the same metallic textures as the main body but added small adjustments. The pipes were given a slightly greasy and dirty look to show their connection to the heart’s inner workings. The gears were textured to feel heavy and solid, with a shiny surface to show their strength and durability. These details helped make the structure of the heart more believable and added more layers to the design without making it feel too chaotic.
