White Expanded Polystyrene Foam PBR Material Set, Granular Texture

This 2K PBR material set provides a realistic white expanded polystyrene foam texture, complete with essential mapping for rendering. The material captures the distinct granular structure of expanded polystyrene, commonly known as styrofoam. It features the characteristic fused bead pattern, presenting a porous and uneven surface finish typical of industrial foam blocks. The white colour is neutral, reflecting light across the irregular surface geometry. This set includes albedo, displacement, normal, roughness, and ambient occlusion maps, allowing for accurate representation of depth and light interaction in a 3D environment. The surface is matte, effectively simulating the non-reflective, lightweight nature of the actual material used widely for protective packaging and thermal insulation.

The download is a 21.4 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 use this PBR set, load the maps into the appropriate channels of your material editor. The displacement map should be assigned to a subdivision or tessellation modifier to achieve the necessary surface depth, while the normal map provides fine-grained detail without increasing geometry count. Adjust the roughness map to fine-tune the matte finish, ensuring the foam reflects light accurately. The tileable nature of these textures allows for seamless application across large surfaces or complex 3D forms.
