This seamless 8K PBR texture represents a weathered limestone surface with a naturally rough and porous stone appearance. Limestone, a sedimentary rock primarily composed of calcium carbonate, exhibits a granular and uneven substrate formed by compacted marine organisms' skeletal fragments. Over time, exposure to environmental conditions results in distinctive weathering patterns, including micro-cracks, pitting, and subtle erosion, all of which contribute to the stone’s characteristic porous texture. The surface finish is matte and unpolished, reflecting the stone’s aged and naturally worn state rather than a refined or brushed look. This texture captures the intricate interplay of light and shadow on the uneven stone face, emphasizing its rugged form and irregular grain.
The material’s composition is defined by a compact yet porous matrix, where the calcium carbonate base is interspersed with fine sediment grains and occasional fossilized inclusions. The porous nature is evident through numerous small holes and crevices, which enhance the tactile roughness and depth. The color palette ranges from pale beige to soft gray tones, with subtle variations caused by natural pigmentation and weathering effects such as mineral stains and surface discoloration. These variations are faithfully represented in the BaseColor (Albedo) channel, while the Normal and Height maps provide detailed surface relief, highlighting cracks, fissures, and stone grain. The Roughness channel accurately simulates the surface’s diffuse reflection properties, ensuring non-metallic, matte characteristics, while the Metallic channel remains low or zero, reflecting the stone’s non-metallic composition. Ambient Occlusion enhances depth perception in crevices and recessed areas, reinforcing the stone’s three-dimensional form.
Designed for high-fidelity applications, this 3D texture integrates seamlessly into Blender, Unreal Engine, and Unity workflows. Its 8K resolution ensures exceptional detail retention even at close camera distances, making it suitable for realistic rock faces, ancient stone walls, architectural facades, or outdoor environmental assets. The seamless tiling capability allows for extensive surface coverage without visible repetition or edge artifacts, supporting large-scale digital environments or scanned asset workflows.
For optimal results, it is advisable to adjust the UV scaling to balance detail density and texture repetition according to the scene’s scale. Additionally, fine-tuning the roughness map can help simulate varying degrees of surface moisture or wear, while blending the height map with normal maps can enhance depth perception without excessive geometry displacement. This approach ensures the weathered limestone texture maintains authenticity and physical plausibility across diverse rendering engines and lighting conditions.
How to Use These Seamless PBR Textures in Blender
This guide shows how to connect a full PBR texture set to Principled BSDF in Blender (Cycles or Eevee). Works with any of our seamless textures free download, including PBR PNG materials for Blender / Unreal / Unity.
What’s inside the download
*_albedo.png — Base Color (sRGB)*_normal.png — Normal map (Non-Color)*_roughness.png — Roughness (Non-Color)*_metallic.png — Metallic (Non-Color)*_ao.png — Ambient Occlusion (Non-Color)*_height.png — Height / Displacement (Non-Color)*_ORM.png — Packed map (R=AO, G=Roughness, B=Metallic, Non-Color)
Quick start (Node Wrangler, 30 seconds)
- Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
- Create a material and select the Principled BSDF node.
- Press Ctrl + Shift + T and select the maps
albedo, normal, roughness, metallic (skip height and ORM for now) → Open.
The addon wires Base Color, Normal (with a Normal Map node), Roughness, and Metallic automatically.
- Add AO and Height using the “Manual wiring” steps below (5 and 6).
Manual wiring (full control)
- Create a material (Material Properties → New) and open the Shader Editor.
- Add an Image Texture node for each map. Set Color Space:
- Albedo → sRGB
- AO, Roughness, Metallic, Normal, Height, ORM → Non-Color
- Connect to Principled BSDF:
albedo → Base Colorroughness → Roughnessmetallic → Metallic (for wood this often stays near 0)normal → Normal Map node (Type: Tangent Space) → Normal of Principled.
If details look “inverted”, enable Invert Y on the Normal Map node.
- Ambient Occlusion (AO):
- Add a MixRGB (or Mix Color) node in mode Multiply.
- Input A =
albedo, Input B = ao, Factor = 1.0.
- Output of Mix → Base Color of Principled (replaces the direct albedo connection).
- Height / Displacement:
Cycles — true displacement
- Material Properties → Settings → Displacement: Displacement and Bump.
- Add a Displacement node: connect
height → Height, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
- Output of Displacement → Material Output → Displacement.
- Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
Eevee (or lightweight Cycles) — bump only
- Add a Bump node:
height → Height.
- Set Strength = 0.2–0.5, Distance = 0.05–0.1, and connect Normal output to Principled’s Normal.
Using the packed ORM texture (optional)
Instead of separate AO/Roughness/Metallic maps you can use the single *_ORM.png:
- Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
- R (red) → AO (use it in the Multiply node with albedo as above).
- G (green) → Roughness of Principled.
- B (blue) → Metallic of Principled.
UVs & seamless tiling
- These textures are seamless. If your mesh has no UVs, go to UV Editing → Smart UV Project.
- For scale/repeat, add Texture Coordinate (UV) → Mapping and plug it into all texture nodes.
Increase Mapping → Scale (e.g., 2/2/2) to tile more densely.
Recommended starter values
- Normal Map Strength: 0.5–1.0
- Bump Strength: ~0.3
- Displacement Scale (Cycles): ~0.03
Common pitfalls
- Wrong Color Space (normals/roughness/etc. must be Non-Color).
- “Inverted” details → enable Invert Y on the Normal Map node.
- Over-strong relief → lower Displacement Scale or Bump Strength.
