What Makes Up a Video Game Character's Appearance? Textures, Models & More

A character's visuals are a pipeline of multiple assets, not a single texture.

Core Components

• 3D Model (Mesh): The geometric skeleton—vertices, edges, faces defining shape (body, clothes, hair). Rigged with a skeleton (bones) for animation.
• Textures (Maps): 2D images wrapped via UV mapping:
  • Albedo/Diffuse: Base color/pattern.
  • Normal Map: Fake surface detail (wrinkles, fabric weave) without geometry.
  • Roughness/Metalness/Specular: How light reacts (shiny metal vs. matte skin).
  • Subsurface Scattering: Skin translucency.
• Materials / Shaders: Code that tells the GPU how to combine textures + lighting + view angle to produce the final pixel. (e.g., "Skin Shader", "Hair Shader", "Cloth Shader").
• Rigging & Animation: Skeleton + weight painting + animation clips (idle, run, attack).
• Particle / FX Attachments: Glowing eyes, aura, dust, magic trails.

Summary

Texture = surface paint. Model = shape. Shader = rendering logic. All three (plus animation) create the character you see.
