The Coarse Straw Seamless Texture offers a highly detailed, organic surface ideal for representing natural hay-straw materials in 3D environments. This texture simulates the fibrous, irregular composition of coarse straw, composed primarily of dried plant stalks with visible grain orientation and subtle waviness. The base substrate is an organic, fibrous material with slight porosity and occasional rough edges, reflecting natural weathering and drying effects. Coloration ranges from warm golden yellows to muted browns, achieved through natural pigments and slight oxidation from exposure. The surface finish is matte with a tactile, slightly rough feel, accurately captured through the texture’s roughness and normal maps, conveying the straw’s uneven, tactile surface without gloss or metallic reflection. Thin binding fibers and occasional dust particles add complexity, enhancing realism across multiple PBR channels.
In physically based rendering workflows, this coarse straw texture excels by delivering comprehensive material data. The BaseColor/Albedo channel presents the warm, earthy tones and subtle color variation found in natural hay-straw, while the Normal map emphasizes the straw’s directional fibers and layered structure, adding convincing depth and relief. The Roughness map controls surface reflectivity, maintaining a natural matte finish with soft highlights where the straw fibers catch light. The Metallic channel is effectively zero, consistent with the non-metallic organic material, while Ambient Occlusion enhances shadowing in crevices between straw bundles to boost realism. The Height/Displacement map provides micro-detail elevation, perfect for adding physical depth in parallax or tessellation shaders. Together, these maps create a seamless coarse straw seamless texture that maintains clarity and cohesion even across large UV islands, making it particularly suitable for modern pipelines in Blender, Unreal Engine, and Unity.
Designed for high-fidelity projects, this tileable coarse straw seamless texture supports resolutions up to 8K, ensuring exceptional detail even on large surfaces. Its seamless nature allows for effortless tiling without visible repetition, enabling quick look-development, environment art, architectural visualization, and concept prototyping workflows. The texture’s micro-detail and structural consistency are the result of an AI-optimized pipeline, enhancing production readiness and visual accuracy. For optimal results, it’s recommended to keep consistent texel density across all assets and maintain uniform UV scaling to avoid pattern stretching. Adjusting the roughness slightly can help tailor the straw’s appearance under different lighting conditions, while subtle use of height or parallax mapping can further enhance the tactile quality of the material in real-time 3D previews and renders.
The ai texture coarse straw seamless texture offers a detailed and realistic PBR appearance that accurately replicates the roughness and fibrous qualities found in natural hay-straw textures, making it ideal for use in material composition and surface rendering.
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.
