How to Texture a Metallic Gun in Blender – Procedural Scratches & Wear (Node-Based)
In this Blender tutorial, you’ll learn how to texture a metallic gun using a fully procedural, node-based workflow, focusing on realistic scratches, edge wear, and surface damage — all without using image textures or texture painting.
The video walks through the complete process step by step: starting with a clean metal base, building procedural scratch masks, edge wear masks, and ambient occlusion masks, and then connecting them correctly to control base color, roughness, metallic response, and normals inside Blender’s Shader Editor. You’ll see how professional node networks are structured and why each connection exists.
You’ll also learn how to fix common procedural texturing issues in Blender, including problems caused by object scale, normals, coordinate space, and topology, and why the same material can behave differently on different objects. A simple procedural wood material is included as well, showing how to create believable wood grain using Noise textures, Mapping nodes, and Bump maps.
This tutorial is ideal for:
– Blender users learning procedural materials
– Hard-surface and game asset artists
– Anyone who wants full control over metal wear and scratches
– Artists moving from image textures to node-based workflows
All texturing is done in Blender Cycles, using shader nodes only — no UV textures, no painting, and no external software required.
If you’re trying to understand how procedural metal materials actually work in Blender, and how to create believable scratched and worn surfaces, this tutorial will give you a solid foundation you can reuse on any hard-surface model.
