This seamless 3D texture in 8K resolution masterfully captures the intricate surface of a natural riverbed ground, composed primarily of small stones and a richly pebbled substrate. The base material replicates a mix of mineral-rich coarse and fine gravel elements embedded within crumbly, organic earth and soil. This combination creates a highly detailed, photorealistic surface that exhibits natural micro-variations in texture and color, ranging from muted browns and grays to subtle earthy tones. The surface finish is matte and slightly rough, reflecting the weathered, porous nature of riverbed terrain shaped by constant water flow and sediment layering over time. The texture’s depth and complexity come from its carefully crafted aggregates and grain orientation, which bring out the tactile quality of the stones and pebbles resting on a softly compacted mineral-organic matrix.
In terms of PBR channels, this texture excels at conveying realism and material authenticity. The BaseColor (Albedo) map presents a balanced palette of natural pigments and oxide layers, highlighting the variations in stone and soil coloration without oversaturation. The Normal map enhances the subtle bumps and indentations of the pebbled surface, while the Roughness channel defines the surface’s matte finish with a finely tuned range from smooth pebbles to rougher gravel patches. The Metallic map is nearly black, accurately representing the non-metallic mineral composition of the riverbed elements. Ambient Occlusion adds depth by simulating the natural shadowing between stones and within crevices, and the Height/Displacement map provides realistic surface relief, perfect for close-up rendering where surface topology is crucial.
Designed for seamless tiling, this riverbed texture integrates flawlessly under neutral lighting conditions without shadows or distracting artifacts, making it ideal for use in natural environment 3D scenes. Its ultra-high 8K resolution ensures exceptional detail even in large-scale applications, and it is fully optimized for compatibility with popular tools like Blender, Unreal Engine, and Unity. For practical use, it is recommended to adjust the UV scale to achieve the best balance between visible detail and performance, and to fine-tune the roughness map to simulate wetness or dryness depending on the scene’s environmental context. This texture provides a versatile, high-quality foundation for any project requiring a realistic, varied, and natural riverbed surface.
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.
