This seamless 8K resolution 3D texture presents a highly detailed and photorealistic depiction of layered altostratus cloud layers, capturing the subtle atmospheric nuances typical of mid-altitude cloud formations. The base material simulates an organic, soft cloud surface with moderate opacity and gently diffused soft edges, reflecting the natural translucency and volume of altostratus clouds. The texture's composition mimics the gradual layering and overlapping of cloud strata, emphasizing the cloud mass's volumetric complexity through carefully calibrated PBR channels. The BaseColor/Albedo map conveys the neutral, muted gray and white pigments characteristic of altostratus clouds, while the Normal and Height maps add realistic depth and volume, simulating the cloud’s evolving surface contours and thickness variations.*
Constructed for photorealistic rendering, this PBR texture features a roughness channel that balances between subtle softness and light diffusion, mimicking the diffuse scattering of sunlight through cloud particles. The Metallic channel remains minimal or unused, as the material is non-metallic and organic in nature, while the Ambient Occlusion map enhances shadow definition within the cloud layers, emphasizing their overlapping and atmospheric depth. The seamless tiling pattern allows for continuous cloud surfaces without visible seams, ideal for expansive sky environments. This texture is optimized for use in Blender, Unreal Engine, and Unity, ensuring compatibility and high fidelity for weather simulations, atmospheric layering, and realistic sky applications.*
The surface finish emulates a soft, diffuse cloud layer rather than a solid or polished surface, with slight porosity suggested by the subtle variations in opacity and translucency. These visual traits are achieved through layered diffuse colorants and simulated volumetric scattering within the texture’s PBR composition. For best results in practical use, adjusting the UV scale can help achieve the desired spatial cloud density, while fine-tuning the roughness value allows for control over how sharply light diffuses through the cloud surfaces. Utilizing the height or parallax map can further enhance the perception of depth and volume in close-up views, making this texture perfect for realistic, immersive atmospheric effects in 3D 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.
