This seamless 3D texture presents a photorealistic PBR 8K depiction of a soft cloudy sky gradient, expertly crafted to simulate the natural interplay of light and atmosphere. The base substrate can be envisioned as a delicate organic layer of diffused airborne moisture particles, suspended within a translucent polymer-like medium that mimics the ethereal quality of sky vapor. Fine cloud highlights emerge from subtle variations in pigment concentration and micro-thin oxide layers, creating gentle luminosity and translucency. The texture’s smooth gradient transitions reflect the gradual color shifts seen during calm sky conditions, enhanced by a neutral, flat lighting setup that accentuates albedo details without introducing shadows or harsh contrasts. These characteristics combine to deliver an authentic, continuous sky surface that blends naturally with surrounding environments, ideal for immersive environmental backgrounds and sky simulations.
In PBR channels, the BaseColor/Albedo conveys soft pastel blues seamlessly merging into pale whites, capturing the essence of a tranquil sky at high resolution. The Normal map encodes delicate cloud edges and volumetric softness, imparting subtle depth and structure without sharp relief, while the Roughness map maintains a smooth, matte finish to replicate the diffuse scattering of light typical of cloudy skies. Metallic values remain minimal to none, preserving the organic, non-reflective nature of atmospheric elements. Ambient Occlusion gently enhances the subtle crevices and folds in cloud formations, adding realism and depth, and the Height/Displacement channel offers slight elevation variations to support parallax effects in close-up renders. This 8K texture is fully optimized and Unreal, Blender, and Unity ready, ensuring seamless integration into modern 3D pipelines with exceptional detail fidelity.
For optimal results, it is recommended to adjust the UV scale to relatively large dimensions to preserve the natural, expansive feel of the sky gradient and avoid repetitive patterns. Fine-tuning the roughness parameter can help balance softness and subtle specular highlights, enhancing the cloud highlights’ realism under various lighting conditions. This high-quality seamless 3D texture is perfect for natural sky and environment renderings where a serene, continuous surface with delicate cloud diffusion and highlights is essential, delivering authentic atmospheric ambiance with professional-grade detail and clarity.
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.
