Texture Mapping

Texture mapping is the process of wrapping 2D images, called textures, onto the surface of a 3D model to give it color, pattern, and material detail. It relies on UV coordinates to determine precisely where each texture lands on the geometry. It is what turns plain geometry into something that reads as wood, metal, skin, or fabric.

Each vertex of a model carries UV coordinates that map it to a position on a 2D texture. During rendering, the shader samples the texture at those coordinates for every surface point, painting the image onto the geometry. Multiple maps can be sampled at once to build a full material.

UV mapping creates the 2D coordinate layout of a model's surface, defining where things can go. Texture mapping is the act of applying actual image maps onto the model using that layout. Clean UVs are a prerequisite for good texture mapping.

A typical PBR material combines base color, or albedo, along with normal, roughness, metallic, and often ambient occlusion maps, all sharing the same UV layout. Together they let the render engine simulate how real materials respond to light.

Beyond standard UV-based mapping, common techniques include planar, cylindrical, and spherical projection for simple shapes, triplanar mapping to avoid seams, and cube or environment mapping for reflections. UV mapping remains the most flexible and widely used for detailed models.

In Blender you unwrap the model's UVs, then build a material in the Shader Editor by connecting image texture nodes for base color, roughness, normal, and other maps to a Principled BSDF shader. You can paint directly on the model with Texture Paint or import maps authored elsewhere.

A texture is a single 2D image such as a color or roughness map. A material is the complete surface definition that combines several textures with shader settings to describe how the surface reacts to light. A material can contain many textures.

UV stretching happens when the UV layout distorts the proportions of the surface, causing textures to smear. You fix it by relaxing or re-unwrapping the UVs, adding seams to reduce distortion, and checking with a test grid texture until the pattern looks even across the model.

Yes. Meshy performs AI texture mapping automatically, generating a complete PBR texture set from a text prompt or reference image and aligning it to your model's UVs. This turns a plain mesh into a fully textured asset and replaces hours of manual texturing.
