White Expanded Polystyrene Foam PBR Material, Granular Texture

This seamless 2K PBR white expanded polystyrene foam material provides a realistic granular surface finish for architectural rendering. This PBR material captures the distinct cellular structure of expanded polystyrene foam. The surface displays a dense, irregular arrangement of fused spherical granules, characteristic of high-density EPS boards used in construction and protective packaging. The material is rendered in a neutral, matte white, exhibiting the subtle light diffusion and shadow depth inherent to this porous plastic. The included maps allow for accurate representation of the material's surface topography, ensuring realistic interaction with light sources. This asset is designed for consistency across large surfaces, maintaining its granular detail without visible repetition in the texture pattern.

The download is a 21.3 MB compressed archive with the texture set at 2K with colour, normal, roughness and displacement maps, ready for any metal/roughness PBR workflow in Blender, 3ds Max, SketchUp, Unreal Engine or D5.

To implement this material, apply the albedo, displacement, normal, and roughness maps to your preferred rendering engine's material node setup. Adjust the displacement map intensity to achieve the desired surface depth and physical relief. The seamless tiling allows for easy application across expansive geometry, such as insulation panels or packaging mock-ups. Ensure correct UV mapping to maintain the scale of the granular nodes, and adjust the roughness parameter to fine-tune the subtle highlight response characteristic of expanded polystyrene.
