This seamless 8k PBR 3d texture captures the authentic surface of a rustic burlap sack, crafted from a woven natural fiber substrate. The base material consists of coarse jute fibers tightly interlaced with twine and rope strands, creating a distinctive, tactile weave pattern. This organic textile features subtle variations in fiber thickness, orientation, and density, reflecting traditional burlap sack construction often used in holiday packaging or rustic decoration. The surface finish is matte and unpolished, exhibiting natural porosity and slight irregularities that contribute to its weathered, handcrafted feel. Earthy beige tones with muted brown pigments highlight the fibers’ natural coloration, while faint dirt accumulation and fiber frays add realism and depth to the overall appearance.
In the PBR workflow, this texture’s BaseColor channel accurately represents the warm, neutral hues and subtle pigment variations of the burlap and twine fibers. The Normal map emphasizes the fabric’s coarse weave and raised rope details, providing pronounced surface relief that interacts realistically with lighting. Roughness values reflect the matte, fibrous surface, ranging from moderately rough fiber bundles to slightly smoother twine strands, with no metallic elements present, so the Metallic channel remains black. Ambient Occlusion enhances shadowing in the crevices of the weave, while the Height/Displacement map conveys the sack’s surface undulations and fiber depth, perfect for subtle parallax effects in real-time engines.
Designed for seamless tiling at an impressive 8k resolution, this PBR texture is fully optimized and ready for integration in Blender, Unreal Engine, and Unity projects. Its high pixel density ensures crisp detail even at close camera distances, making it ideal for 3D models requiring an authentic natural textile surface, especially in Christmas or holiday-themed environments. For best results, consider adjusting the UV scale to match the typical fiber size of burlap sacks and fine-tune roughness to balance between fabric softness and coarse texture. Utilizing the Height map for parallax occlusion can further enhance the tactile quality, adding depth to your renders while maintaining efficient performance across platforms.
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.
