Explore popular metal texture types

Brushed steel and aluminum textures

Directional scratches and controlled roughness suit machinery, appliances, trim, and manufactured props.

Rusted and weathered metal textures

Oxidation, chipped coatings, and exposed edges distinguish aged metal from a uniformly clean reflective surface.

Metal panel and diamond plate textures

Raised tread, ribbing, perforations, and panel seams give industrial floors and walls a recognizable construction pattern.

How to choose a metal texture

Mask coatings separately from bare metal

Paint and rust should not share the same metallic value as exposed steel. Review the metallic mask wherever the surface changes from a coating to bare metal.

Control highlights with roughness

Judge the surface under more than one lighting setup. A brushed finish needs directional detail and believable roughness rather than bright reflections baked into its color image.

Where metal textures fit

  • Industrial panels and machinery
  • Weapons, vehicles, and hard-surface props
  • Worn, rusted, and oxidized materials
  • Metallic-roughness PBR workflows

Metal texture FAQ

What makes a texture into a PBR metal material?

A PBR metal material uses base color, metallic, and roughness together to describe reflection, with normal or height for relief. A photo of shiny metal alone contains lighting that may need removal before it works as a material source.

Should rust and painted metal be metallic?

In a metallic-roughness workflow, exposed metal is metallic while paint and ordinary rust layers are treated as non-metallic. Use a mask to separate these areas instead of applying one metallic value to the whole surface.
