This seamless 8k PBR 3D texture portrays a stormy sky dominated by dense, dark thunderstorm clouds interspersed with vivid lightning strikes. The material is conceptually based on a volumetric, amorphous cloud substrate composed of turbulent vapor formations, with no rigid geometric pattern but rather a fluid, organically layered structure. The “surface” is metaphorically treated as a dynamic sky dome, where the interplay of light and shadow sculpts the volumetric shapes of cumulonimbus clouds. The texture simulates the diffusion and scattering properties of water vapor particles suspended in the atmosphere, with subtle gradations of opacity and translucency contributing to the realistic depth and volume effect.
From a materials perspective, the texture’s base color (Albedo) channel captures the nuanced color palette of storm clouds—deep grays, muted blues, and near-black shadows—punctuated by bright, desaturated white lightning highlights. The Normal map encodes fine volumetric undulations and turbulent eddies within the cloud mass, enhancing the three-dimensional illusion of depth and motion. Roughness is carefully calibrated to reflect the diffuse scattering of light by the water droplets, resulting in a soft, matte finish with minimal specular highlights, while the Metallic channel remains at zero to represent the non-metallic, gaseous nature of the sky. Ambient Occlusion adds subtle shading to emphasize cloud density variations and crevices, improving visual contrast. Height or Displacement maps simulate the billowing, towering forms of storm clouds, allowing for realistic parallax effects when rendered in 3D environments.
The texture is optimized for high-detail workflows, with its ultra-high 8k resolution ensuring exceptional clarity and fidelity when applied to expansive sky domes or panoramic skyboxes. It is fully compatible with major 3D engines such as Blender, Unreal Engine, and Unity, facilitating seamless integration into weather simulations, cinematic visual effects, and immersive game environments. The seamless tiling ensures that large-scale scenes maintain continuity without visible repetition or artifacts, vital for realistic environmental lighting and reflections.
When applying this texture, it is recommended to carefully adjust the UV scale to balance detail density and performance, especially for close-up camera work. Fine-tuning roughness values can enhance the subtle interplay between cloud softness and lightning brightness, while blending height and normal maps can improve the volumetric perception of cloud layers. These adjustments allow artists and developers to accurately replicate the unpredictable and dynamic nature of stormy skies within their digital scenes.
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.
