Seamless 3D Alcohol Ink PBR Texture Featuring Vibrant Rainbow Fluid Marbling and Soft Cellular Edges free download

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.
