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)

1. Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
2. Create a material and select the Principled BSDF node.
3. 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.
4. Add AO and Height using the “Manual wiring” steps below (5 and 6).

Manual wiring (full control)

1. Create a material (Material Properties → New) and open the Shader Editor.
2. Add an Image Texture node for each map. Set Color Space:
   • Albedo → sRGB
   • AO, Roughness, Metallic, Normal, Height, ORM → Non-Color
3. Connect to Principled BSDF:
   • albedo → Base Color
   • roughness → Roughness
   • metallic → 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.
4. 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).
5. Height / Displacement:
   Cycles — true displacement

   1. Material Properties → Settings → Displacement: Displacement and Bump.
   2. Add a Displacement node: connect height → Height, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
   3. Output of Displacement → Material Output → Displacement.
   4. Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
   Eevee (or lightweight Cycles) — bump only

   1. Add a Bump node: height → Height.
   2. 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:

1. Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
2. R (red) → AO (use it in the Multiply node with albedo as above).
3. G (green) → Roughness of Principled.
4. B (blue) → Metallic of Principled.

UVs & seamless tiling

1. These textures are seamless. If your mesh has no UVs, go to UV Editing → Smart UV Project.
2. 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.
