This seamless 3D PBR texture at an impressive 8K resolution depicts a dense nimbostratus cloud mass with a richly overcast and stormy atmospheric appearance. The material emulates a volumetric organic surface formed by tightly packed water vapor and condensation particles, creating a heavy-opacity cloud layer typical of nimbostratus formations. Its base substrate can be conceptually understood as a finely dispersed polymeric aerosol medium, bound by microscopic moisture adhesion forces that generate subtle turbulence and layered volumetric effects. The texture’s gray-scale tonal range reflects the natural gradation of cloud density, capturing the nuanced interplay of light diffusion and absorption without distinct shadows or highlights, which ensures a neutral albedo ideal for realistic weather front visualizations in 3D environments.
From a materials perspective, the texture’s photorealistic PBR channels carefully map these atmospheric qualities: the BaseColor/Albedo channel presents a soft, muted gray palette representing the dense condensation layers, while the Normal map conveys delicate surface irregularities and turbulent cloud formations that add depth and realism. The Roughness channel varies subtly to simulate the uneven scattering of light through the cloud mass, avoiding glossy reflections to maintain the matte, diffused appearance characteristic of storm clouds. Metallic is kept at zero, consistent with the non-metallic, organic nature of clouds, while Ambient Occlusion enhances the perception of volume and overlapping cloud layers. The Height/Displacement map provides fine vertical relief to simulate the cloud mass’s layered structure, enriching the volumetric realism especially when used with parallax or displacement techniques.
This texture is fully optimized and ready for seamless tiling, making it perfect for use in Blender, Unreal Engine, and Unity projects where large-scale stormy skies or weather fronts are required. Its high 8K resolution ensures that close-up renderings retain crisp detail, capturing the subtle turbulence and dense layering without pixelation. For practical integration, adjusting the UV scale can help tailor the cloud mass density to suit specific scene requirements, and modulating roughness parameters allows for fine-tuning the balance between softness and atmospheric diffusion. This seamless 3D PBR texture is a versatile material asset that enhances any environment needing realistic, dense nimbostratus cloud surfaces with rich volumetric depth and stormy overcast qualities.
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.
