White Expanded Polystyrene Foam PBR Material, Uniform Granular Surface

This white expanded polystyrene foam PBR material provides a 2K resolution texture set for realistic synthetic surface rendering. This PBR material replicates the characteristic granular texture of expanded polystyrene foam. The surface features a dense, uniform arrangement of small, spherical beads, typical of industrial-grade styrofoam used in packaging and thermal insulation. Its neutral white colouration ensures versatility across various lighting conditions. The set includes essential maps for albedo, displacement, normal, roughness, and ambient occlusion, allowing for precise control over the material's physical response to light. The visual density of the beads is consistent, providing a convincing representation of the material's porous yet structured composition when applied to complex geometries or flat panels.

The download is a 23.4 MB compressed archive with the texture set at 2K with colour, normal, roughness, ambient occlusion and displacement maps, ready for any metal/roughness PBR workflow in Blender, 3ds Max, SketchUp, Unreal Engine or D5.

To implement this material, load the provided maps into your render engine's shader node editor. Assign the albedo to the base colour, and use the normal and displacement maps to generate depth and surface irregularity at render time. The roughness map should be plugged into the specular or glossiness channel to accurately simulate the subtle light scattering of the foam beads. Adjust the displacement scale based on the desired level of surface relief for close-up or long-range shots.
