This seamless 8k PBR 3D texture represents a tropical sky dome featuring a clear, expansive blue backdrop punctuated by voluminous cumulus clouds and a vibrant sun flare. The base material emulates an atmospheric volume formed by air particles with suspended water vapor, rendered here as a smooth gradient substrate combined with soft, billowy cloud masses. These clouds exhibit subtle translucency and varying density, achieved through carefully crafted normal and height maps that simulate their fluffy, three-dimensional form. The overall geometric pattern is amorphous and organic, reflecting natural sky formations without repetitive tiling artifacts, making this texture ideal for skyboxes or panoramic backgrounds.
From a materials perspective, the substrate can be understood as a thin optical layer with a diffused scattering effect, enhanced by layered alphamaps that replicate the semi-transparent qualities of moisture-laden air. The clouds themselves behave as aggregates of micro-droplets, modeled via finely detailed normal and displacement maps that provide depth and soft edges. The color composition relies on a gradient of blue hues for the BaseColor (Albedo) channel, transitioning from deep cerulean at the zenith to lighter cyan near the horizon, combined with white and subtle gray tones for cloud shading. The roughness channel is tuned to moderate values, reflecting the diffuse scattering of sunlight across the sky and clouds, while the metallic channel remains near zero, as sky elements do not exhibit metallic properties. Ambient Occlusion maps subtly enhance the shadowing beneath cloud masses to increase depth perception, and the height/displacement channel accentuates the volumetric form of cumulus clouds, enabling realistic parallax effects in 3D environments.
The surface finish is inherently matte with soft gradients and no glossiness, consistent with natural atmospheric scattering. Weathering effects are minimal since the sky is a dynamic, ever-changing form; however, the texture simulates slight variations in cloud density and sun flare intensity to evoke natural sunlight diffusion and atmospheric clarity. The high 8k resolution ensures that fine details in cloud edges and sun flare gradients remain crisp and visually convincing even at close camera angles, making this texture suitable for high-fidelity renders and real-time engines.
Designed for seamless tiling in Blender, Unreal Engine, and Unity, this sky texture fits perfectly on sky domes or large environmental spheres, providing a realistic backdrop for outdoor scenes. For practical application, it is advisable to carefully adjust the UV scale to avoid stretching the cloud formations and to fine-tune the roughness channel to match the desired atmospheric clarity or haze. Additionally, blending height and normal maps can enhance the volumetric feel of clouds, especially when paired with parallax occlusion shaders, to improve depth realism in interactive 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.
