For Architectural Visualization
Premium PBR Textures for Real-Time Engines
Surface Realism That Passes the 100% Zoom Test
GrainStack captures the microscopic imperfections that make architectural renders believable, from the subtle grain variation in reclaimed white oak to the precise oxidation patterns on weathered Corten steel.
Every material is captured on Phase One IQ4 150MP medium-format cameras and processed through a proprietary multi-pass workflow. You receive 8K seamless tiles with dedicated albedo, roughness, metallic, normal, and 16-bit displacement maps. Interior studios rely on our micro-cement and brushed brass collections to eliminate the plastic look in close-up camera pans, while exterior architects use our weathered concrete and hand-formed terracotta sets to ground site masterplans in tangible reality.
True-to-Life Scale and Seamless Tiling
No more guessing tile sizes or stretching seams across façade panels. Every GrainStack asset is baked to exact real-world measurements and optimized for infinite repetition without visible gridding.
Our 600mm×600mm ceramic porcelain collection matches industry-standard manufacturing tolerances down to the millimeter. Large-format slate and modular brick sets include pre-configured UV layouts that align perfectly with standard 2x4 framing and traditional masonry courses. When you scale a material in Unreal Engine 5 or Lumion, the displacement maps respond proportionally, ensuring that a 45-degree camera angle reveals accurate depth and shadow falloff across every surface.
Physically Based Lighting for Real-Time Workflows
Materials that react to light exactly as they do in the physical world, optimized for UE5, Blender Cycles, and V-Ray GPU rendering pipelines.
GrainStack adheres to strict glTF 2.0 and Unity HDRP conventions for every map channel. Our roughness maps are pre-converted to sRGB with accurate microfacet distribution, so a polished travertine floor reflects HDRI skyboxes with correct falloff, and a matte lime plaster wall diffuses sunlight without unwanted specular hotspots. Studio lighting setups require zero manual tweaking—just drop the texture pack into your material graph and let the engine handle the optics.
