Free Glass PBR Textures (Seamless • 2K–4K)

Discover a curated library of free Glass PBR textures for windows, partitions, shower screens, bottles and decorative panels. Most entries include Base Color (Albedo) (when relevant), Normal, Roughness, Height/Displacement and Ambient Occlusion. Materials are tileable and optimized for crisp results in Blender, Unreal, Unity and D5 Render.

Tips for realistic glass

  • Use Transmission=1.0 and IOR ≈ 1.45–1.52 (glass) in Principled BSDF.
  • Drive blur with Roughness: 0.0 (clear), 0.1–0.4 (frosted), 0.4–0.7 (opaque frosted).
  • Keep Normal subtle (small strength) to avoid wavy distortions unless desired.
  • Add thickness for physically-correct refraction; avoid single-sided planes for hero shots.
  • For real-time, enable refraction/SSR and tweak translucency; in path tracers, allow caustics where needed.
  • Patterned/frosted glass: use an opacity (alpha) mask or normal-based micro-roughness map.

FAQ

Which maps are included?
Typically Normal, Roughness, Height/Displacement and AO; Albedo is included when relevant (e.g., tinted or patterned glass).

Are these textures seamless?
Yes, where applicable. Patterned/frosted variants are prepared for tiling on large surfaces.

How do I get clean refractions?
Model thickness, set a correct IOR and reduce normal strength. Use higher samples for caustics if needed.

Performance tips?
In real-time engines, limit refraction rays, use screen-space refraction and keep roughness-driven blur moderate.
