This seamless 8K PBR texture captures the intricate details of gravel tire marks impressed upon a rugged gravel road track. The base material consists primarily of loose, angular gravel aggregates embedded within a compacted soil substrate. These gravel particles vary in size and shape, ranging from small pebbles to coarser stones, creating a naturally uneven and porous surface. The soil acts as a binder, holding the gravel in place, with subtle variations in moisture and dryness contributing to the overall texture. The tire tread detail is sharply defined, showing repeated patterns of vehicle imprints that compress the gravel and dust, displacing finer particles and leaving behind distinctive dry tire tracks. The surface finish is matte and rough, reflecting the dusty, weathered nature of an outdoor gravel road subject to frequent vehicular traffic and natural erosion.
From a PBR material perspective, the BaseColor (Albedo) map accurately reproduces the muted earth tones of the gravel and soil, including subtle color shifts caused by dust accumulation and dry patches. The Normal map enhances the perception of depth and relief by emphasizing the raised gravel clumps and recessed tire tread impressions, providing realistic surface undulations. Roughness values are generally high, representing the coarse, non-reflective nature of gravel and road dust, while small variations in roughness simulate areas where gravel is more compacted or where dust has settled unevenly. The Metallic channel remains near zero, reflecting the non-metallic organic and mineral composition of the road surface. Ambient Occlusion is subtly integrated to accentuate crevices and tire track depressions, increasing the realism of shadowed areas. The Height or Displacement map captures the three-dimensional aspects of gravel piles and tire indentations, allowing for precise parallax or tessellation effects.
Designed for seamless repetition, this texture is optimized for use in Blender, Unreal Engine, and Unity, supporting large-scale outdoor scenes such as offroad vehicle trails and rugged gravel paths. The 8K resolution ensures that fine details remain crisp even at close camera distances, preserving the tactile quality of gravel grains and tire tread patterns. Neutral lighting in the source imagery ensures adaptability across various environmental lighting conditions, from bright daylight to overcast scenarios, without color bias.
For practical application, it is advisable to carefully adjust the UV scale to match the actual size of gravel and tire tread in the scene, preventing pattern stretching or repetition artifacts. Additionally, fine-tuning the roughness map can help simulate different weathering states—for example, increasing roughness for drier, dustier conditions or slightly reducing it where gravel appears damp or compacted. Combining height and normal maps with parallax occlusion mapping can further enhance the three-dimensional feel of tire imprint depressions and gravel texture depth, adding realism to vehicle track visualizations in interactive environments.
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.
