• Source materials are defined in VMT files.
• Source 2 materials are defined in VMAT files.

GoldSrc does not use materials; instead, textures are used directly, and flagged either via name in a WAD or by metadata in an MDL or SPR. Information about a texture's "material" is instead stored in materials.txt and MAT files. If a material is missing, it will produce the infamous Source pink and black checkered pattern. A white wireframe is not a missing shader, but instead a missing shader.

Risk of Confusion:This page is for the concept of materials in general. More information about materials in specific engines can be found on the documentation about the specific engines' material format pages.
