How to texture a 3D model in character design?

In character design, texturing a 3D model involves creating UV maps (to unfold the 3D surface into 2D) and applying 2D texture files (like diffuse for color, normal for depth, specular for shine) via software to add visual detail and material properties. UV mapping ensures textures align correctly—use tools (e.g., Blender, Substance Painter) to mark seams, unwrap, and layout UVs. Next, apply textures: diffuse sets base color, normal mimics small details (wrinkles/scales), and specular controls light reflection (shiny vs. matte). For beginners, start with a simple character in Blender: use "Smart UV Project" for basic unwrapping, then try Texture Paint mode to draw colors directly—this practices UV-texture alignment without complexity.
