This seamless 8K PBR 3D texture captures the intricate formation of slate, a sedimentary rock known for its characteristic layered structure and natural flat slabs. Slate originates from fine-grained clay minerals compressed over time into thin, durable sheets that form the base material. These sheets exhibit a subtle stratification pattern, with variable thicknesses and slight irregularities that create an authentic sense of geological layering. The texture reveals a combination of smooth, flat surfaces interrupted by rougher, weathered slab edges, mimicking natural fractures and surface erosion commonly found in outdoor stone formations.
The composition reflects a complex interplay between the stone’s mineral substrate and its surface features. The base color channel (Albedo) presents a range of muted greys and subtle color variations typical of slate, influenced by mineral impurities and organic matter trapped during sedimentation. The Normal map enhances the perception of these layered ridges and the uneven slab surfaces, adding depth and tactile realism. Roughness maps delineate areas of polished flatness versus coarse, granular patches where natural weathering has increased surface texture, while the Height and Ambient Occlusion maps emphasize crevices and subtle elevation changes between stacked stone slabs. The Metallic channel remains close to zero, consistent with the non-metallic, earthy nature of the rock.
The texture’s form is defined by the arrangement of flat, planar slabs stacked or layered with slight offsets, reflecting the natural fissility of slate. This pattern creates a visually appealing geometric repetition ideal for stone tile floors, rock facades, or stacked stone walls in digital environments. The surface finish is matte and rough, lacking glossiness, which enhances realism in outdoor scenes exposed to the elements. Fine grain and porosity details are subtly visible, contributing to believable light scattering and shadowing effects, especially when rendered with advanced PBR workflows.
With an ultra-high 8K resolution, this texture is optimized for use in Blender, Unreal Engine, and Unity, ensuring crisp detail and scalability for close-up renders or expansive architectural visualizations. Its seamless design guarantees smooth tiling across large surfaces without visible seams or pattern repetition. For practical application, adjusting the UV scale can prevent noticeable texture repetition on larger models, and fine-tuning the roughness map can simulate varying degrees of wetness or dryness on the stone surface. Additionally, blending Height and Normal maps allows enhanced parallax effects, adding dimensionality to flat surfaces without heavy geometry.
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.
