The blackened steel oil tempered texture is a finely crafted metal surface that showcases the distinct characteristics of steel treated through oil tempering, a process that enhances both durability and aesthetic appeal. This texture features a base substrate of tempered steel, known for its strength and resilience, combined with a dark, oxidized patina formed by the oil tempering process. The surface finish exhibits a subtle interplay of polished and matte areas, where the oil tempering creates a nuanced, blackened coloration with faint metallic highlights and slight grain orientation visible beneath the surface. The texture’s porosity is minimal, reflecting the dense and compact nature of tempered steel, while fine surface imperfections and controlled noise add realism without compromising the clean, seamless appearance. The resulting metal surface is ideal for realistic simulations of industrial, architectural, or product design projects requiring authentic blackened steel surfaces.
In physically based rendering workflows, this seamless blackened steel oil tempered texture is supported by a comprehensive set of PBR maps, including BaseColor (Albedo), Normal, Roughness, Metallic, Ambient Occlusion, and Height/Displacement. The BaseColor channel captures the dark, muted tones and subtle color variations inherent to the oil-tempered finish, while the Normal map emphasizes the delicate grain and surface irregularities that give the steel its tactile quality. The Roughness map balances areas of soft reflection with slightly rougher patches to simulate the tempered surface’s light scattering, and the Metallic map confirms the steel’s fully metallic nature with consistent, high reflectivity values. Ambient Occlusion enhances depth perception by simulating soft shadows in crevices and edges, while the Height/Displacement map provides fine surface relief, enabling realistic light interaction and parallax effects, especially useful in close-up renders.
Rendered at resolutions up to 8K, this tileable blackened steel oil tempered texture delivers exceptional detail and clarity, ensuring crisp and lifelike visuals across large surfaces without visible seams or repetition artifacts. It is fully optimized for seamless integration with major 3D engines such as Blender, Unreal Engine, and Unity, supporting real-time 3D preview workflows and efficient project iteration. For optimal results, adjusting the roughness intensity to suit specific lighting conditions and carefully scaling UV coordinates can prevent texture distortion and maintain the natural appearance of the blackened steel pattern. This texture is an excellent choice for enhancing architectural visualizations, game environments, and product mockups, providing a sophisticated, high-quality metal surface that responds realistically under diverse lighting setups.
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.
