■ TEXTURES VS MATERIALS There is a difference between textures and materials in UDK. Textures (a single file)

• It is usually a diffuse, specular or normal map file that you would create in Photoshop.

Materials • made up of various textures combined together inside the

Material Editor in UDK. • use to apply on your BSP geometry or Static Meshes.
