This perforated overlapping circle brass sheet texture is crafted from a finely engineered metallic base substrate, primarily composed of high-quality brass alloys that blend copper and zinc. This composition imparts a warm golden hue with natural variations subtly enhanced by controlled oxidation and surface treatments. The sheet features a unique pattern of overlapping circular perforations, which not only elevate the material’s visual appeal but also contribute functional benefits such as improved ventilation or reduced weight. The surface finish balances polished and brushed brass characteristics, resulting in a slight sheen that avoids excessive glare while maintaining a tactile richness. These carefully designed surface properties reflect the brass’s inherent qualities, including its warmth, resilience, and distinctive metallic luster.

The texture achieves exceptional realism through detailed Physically Based Rendering (PBR) maps that capture every nuance of the brass sheet’s surface. The BaseColor (Albedo) map reveals the subtle shifts in tone caused by oxidation and brushing, emphasizing the warm golden color and natural wear. Normal maps highlight the depth and dimension of the perforations and the sheet’s minor surface irregularities, enhancing the three-dimensional feel. Roughness is precisely calibrated to reflect the semi-gloss finish, allowing natural highlights and soft reflections to appear realistically across the material. The Metallic map underscores the conductive properties of brass, while Ambient Occlusion accentuates the shadows around each perforation, adding depth and contrast. The Height/Displacement map provides accurate elevation data, enabling detailed parallax and displacement effects that further enhance realism in 3D environments.

Rendered at an impressive 8K resolution, this seamless brass sheet texture is optimized for high-end visualization workflows and real-time applications, making it compatible with major 3D platforms such as Blender, Unreal Engine, and Unity. This ensures consistent visual quality and performance across diverse projects, from architectural visualization to product design and game asset creation. The texture’s parametric design allows easy customization, with UV scaling adjustments enabling users to control the pattern density and alignment of the overlapping perforations. For best results, it is recommended to fine-tune the roughness channel based on the desired surface condition—whether simulating a freshly polished brass sheet with a smooth, reflective finish or a more aged, matte look with subtle wear.

How to Use These Seamless PBR Textures in Blender

This guide shows how to connect a full PBR texture set to Principled BSDF in Blender (Cycles or Eevee). Works with any of our seamless textures free download, including PBR PNG materials for Blender / Unreal / Unity.

What’s inside the download

  • *_albedo.png — Base Color (sRGB)
  • *_normal.png — Normal map (Non-Color)
  • *_roughness.png — Roughness (Non-Color)
  • *_metallic.png — Metallic (Non-Color)
  • *_ao.png — Ambient Occlusion (Non-Color)
  • *_height.png — Height / Displacement (Non-Color)
  • *_ORM.png — Packed map (R=AO, G=Roughness, B=Metallic, Non-Color)

Quick start (Node Wrangler, 30 seconds)

  1. Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
  2. Create a material and select the Principled BSDF node.
  3. Press Ctrl + Shift + T and select the maps albedo, normal, roughness, metallic (skip height and ORM for now) → Open. The addon wires Base Color, Normal (with a Normal Map node), Roughness, and Metallic automatically.
  4. Add AO and Height using the “Manual wiring” steps below (5 and 6).

Manual wiring (full control)

  1. Create a material (Material Properties → New) and open the Shader Editor.
  2. Add an Image Texture node for each map. Set Color Space:
    • AlbedosRGB
    • AO, Roughness, Metallic, Normal, Height, ORMNon-Color
  3. Connect to Principled BSDF:
    • albedoBase Color
    • roughnessRoughness
    • metallicMetallic (for wood this often stays near 0)
    • normalNormal Map node (Type: Tangent Space) → Normal of Principled. If details look “inverted”, enable Invert Y on the Normal Map node.
  4. Ambient Occlusion (AO):
    • Add a MixRGB (or Mix Color) node in mode Multiply.
    • Input A = albedo, Input B = ao, Factor = 1.0.
    • Output of Mix → Base Color of Principled (replaces the direct albedo connection).
  5. Height / Displacement:
    Cycles — true displacement
    1. Material Properties → SettingsDisplacement: Displacement and Bump.
    2. Add a Displacement node: connect heightHeight, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
    3. Output of Displacement → Material Output → Displacement.
    4. Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
    Eevee (or lightweight Cycles) — bump only
    1. Add a Bump node: heightHeight.
    2. Set Strength = 0.2–0.5, Distance = 0.05–0.1, and connect Normal output to Principled’s Normal.

Using the packed ORM texture (optional)

Instead of separate AO/Roughness/Metallic maps you can use the single *_ORM.png:

  1. Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
  2. R (red) → AO (use it in the Multiply node with albedo as above).
  3. G (green) → Roughness of Principled.
  4. B (blue) → Metallic of Principled.

UVs & seamless tiling

  1. These textures are seamless. If your mesh has no UVs, go to UV EditingSmart UV Project.
  2. For scale/repeat, add Texture Coordinate (UV)Mapping and plug it into all texture nodes. Increase Mapping → Scale (e.g., 2/2/2) to tile more densely.

Recommended starter values

  • Normal Map Strength: 0.5–1.0
  • Bump Strength: ~0.3
  • Displacement Scale (Cycles): ~0.03

Common pitfalls

  • Wrong Color Space (normals/roughness/etc. must be Non-Color).
  • “Inverted” details → enable Invert Y on the Normal Map node.
  • Over-strong relief → lower Displacement Scale or Bump Strength.
