This seamless 3D texture of glowing embers in 8K resolution is designed to faithfully replicate the intricate composition and visual complexity of a smoldering ember surface. At its core, the material emulates an organic mineral substrate formed by partially burnt carbonized wood fragments bonded together with fine ash particles and residual resinous binders. The texture captures the porous, weathered nature of embers with subtle micro-cracks and fissures where incandescent heat radiates. The surface finish appears matte with slight variations in roughness, mimicking the natural charred texture and scattered fire sparks glowing faintly throughout. Dark iron oxide pigments and subtle reddish-brown colorants blend throughout the base albedo, creating the deep ember hues that shift realistically under lighting conditions.
In the PBR workflow, the BaseColor (Albedo) channel reveals the rich ember tones and nuanced color gradients from deep reds to near-black char, avoiding any visible tiling thanks to its seamless design. The Normal map enhances the perception of fine surface irregularities such as cracks, grain orientation, and subtle embers’ contours, adding depth to the texture under dynamic lighting. The Roughness map varies realistically to reflect areas of cooled ash with higher roughness, contrasting with lower roughness zones where glowing heat suggests a smoother, molten-like surface. The Metallic channel remains near zero, consistent with the organic non-metallic nature of embers. Ambient Occlusion emphasizes the crevices and porous details, enhancing the overall depth and realism, while the Height/Displacement channel accurately simulates the subtle elevation changes of the cracked ember surface, enriching parallax effects in 3D applications.
Rendered in ultra-high 8K resolution, this texture is optimized for seamless tiling and ready to use in popular engines such as Unreal Engine, Blender, and Unity, ensuring maximum fidelity in fire and heat-based visual effects. The high resolution allows for close-up inspection without loss of detail, crucial for realistic fire simulations, game environments, or cinematic VFX. For best results, adjusting the UV scale to a medium range maintains natural ember proportions, while fine-tuning roughness can simulate different stages of ember cooling or ignition. Additionally, employing the height map with parallax occlusion mapping enhances the immersive feel of the glowing surface under varying viewpoints.
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.
