These acoustical eggcrate foam panels consist primarily of a lightweight, polymer-based substrate engineered for superior sound absorption and diffusion. The base material is typically composed of polyurethane or melamine resin, forming a durable foam matrix that is precisely molded or cut into the signature eggcrate pattern. This open-cell structure significantly enhances porosity, allowing sound waves and air to penetrate deeply and dissipate efficiently, which improves acoustic performance by reducing echoes and ambient noise. The panels are bonded using minimal adhesive additives to preserve the foam’s natural flexibility and resilience, ensuring long-lasting durability without compromising softness or structural integrity. During manufacturing, carefully integrated pigments provide a consistent, subtle off-white or light gray hue, contributing to the material’s natural appearance and ensuring uniform coloration across the surface. The finish is matte and slightly textured, deliberately avoiding gloss to minimize unwanted light reflections and visually reinforce the panel’s acoustic function.

In the physically based rendering (PBR) workflow, these panels are captured with advanced texture maps to reflect their detailed surface composition accurately. The BaseColor (Albedo) map records the foam’s subtle, uniform color and fine textural nuances inherent to the polymer matrix. The Normal map intricately simulates the distinctive eggcrate relief, highlighting the sharp ridges and deep cavities with high precision to enhance three-dimensional depth. Roughness values are calibrated high to represent the foam’s soft, non-reflective surface, effectively reducing specular highlights and contributing to a natural matte appearance. The Metallic channel remains near zero, reflecting the non-metallic nature of the polymer foam. Ambient Occlusion intensifies the perception of depth within the grooves and recesses, while Height or Displacement maps add realistic volume and contour detail, enabling enhanced parallax effects for close-up views in 3D environments.

Rendered in seamless, high-resolution textures up to 8K, these acoustical eggcrate foam panels are fully optimized for integration into Blender, Unreal Engine, and Unity platforms, supporting realistic architectural visualization, game design, and virtual reality simulations. To achieve the best visual fidelity, it is recommended to carefully adjust UV scaling to maintain the natural proportions of the eggcrate pattern and fine-tune roughness levels to balance diffuse scattering with subtle light interaction. Additionally, utilizing Height or Displacement maps in conjunction with parallax occlusion mapping can substantially elevate the tactile realism of these foam panels, especially in close-up shots, enhancing immersion and material authenticity in digital scenes.

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.
