These acoustical eggcrate foam tiles are expertly crafted from a polymer-based foam substrate engineered specifically for superior sound absorption and diffusion. The lightweight, open-cell structure is achieved through a specialized foaming process that creates the distinctive eggcrate pattern, maximizing surface area and porosity to enhance acoustic performance. Flexible polymer binders within the foam matrix allow it to effectively trap and dissipate sound waves, reducing echo and reverberation in various indoor environments. The surface finish features a matte, slightly textured appearance that enhances its non-reflective properties, contributing to realistic shading and subtle tonal variations in digital visualizations. The soft off-white color results from stable pigments that resist fading and discoloration over time, ensuring consistent appearance under diverse lighting conditions and prolonged use.

In physically based rendering (PBR) workflows, the texture channels meticulously capture the material’s unique characteristics. The BaseColor or Albedo channel records the subtle tonal shifts and soft shadows caused by the eggcrate peaks and valleys, while the Normal map defines the intricate three-dimensional relief of the foam’s convoluted surface. The Roughness map reflects the foam’s low-gloss, porous nature, creating diffuse reflections ideal for acoustic panel representation. The Metallic channel remains unused due to the non-metallic polymer composition, whereas the Ambient Occlusion channel enhances depth perception by emphasizing crevices between the ridges. Additionally, the Height or Displacement map provides detailed elevation data that improves realism when paired with parallax occlusion or tessellation techniques, making this texture well-suited for rendering engines such as Blender, Unreal Engine, and Unity. Available at ultra-high 8K resolution, these seamless tiles maintain crisp detail and clarity even in close-up shots or large-scale architectural visualizations.

For best results, carefully scale the UV mapping to preserve the proportional integrity of the eggcrate pattern relative to the surrounding geometry, preventing visual distortion that could detract from immersion. Slightly increasing roughness values can simulate the foam’s subtle surface softness, while utilizing the height map can add convincing tactile depth to the acoustic panel’s appearance. This PBR texture set is ideal for realistic visualizations requiring authentic acoustical materials, such as architectural interiors, game environments, and product renderings where detailed soundproofing elements are essential without compromising visual fidelity or performance.

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.
