This seamless 3D texture of fire glow and radiant heat surface is meticulously crafted to represent the complex materials and composition of a glowing ember-like substrate. The base material emulates a porous, mineral-based surface imbued with organic charred elements and fine ash particles. Within the texture, subtle binders and adhesive-like residues simulate the natural cohesion of combusted fibers and mineral aggregates, creating a realistic charred matrix. The surface finish combines a lightly oxidized, matte quality with intermittent glossy patches where incandescent firelight intensifies, reflecting the dynamic interplay of heat and flame. Warm pigments of orange, red, and yellow oxide layers are carefully blended to produce a photorealistic fire glow that radiates from the texture, capturing the subtle variations in temperature and combustion stages.
In terms of PBR channels, this 8K resolution texture excels in delivering fine detail and realism. The BaseColor/Albedo channel showcases the warm flame tones and natural heat emission colors without baked lighting, ensuring versatility under neutral lighting setups. The Normal map conveys intricate surface irregularities and fine grain orientation that mimic the fibrous, cracked structure of burning material. Roughness values vary to reproduce the contrast between matte ash-coated areas and the smoother, molten patches, while the Metallic channel remains near zero to reflect the non-metallic nature of the fire-affected surface. Ambient Occlusion enhances the depth of crevices and porous regions, and the Height/Displacement map adds convincing surface relief for parallax effects, enhancing immersion in digital environments.
Rendered in photorealistic 8K resolution, this texture is fully optimized for seamless tiling, making it ideal for use in advanced workflows such as Unreal Engine, Blender, and Unity. Its clean, albedo-only approach allows for flexible lighting adjustments, ensuring that fire glow and radiant heat effects can be realistically integrated into games, simulations, or digital art scenes without visual artifacts. For best results, adjusting the UV scale to a finer detail level enhances the appearance of the porous, charred surface, while fine-tuning the roughness map can emphasize either the soft glow of heat waves or the harsher, cracked charcoal areas, depending on the artistic direction.
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.
