Material Library Loader — Auto-build PBR materials in Blender
Stop wiring shaders by hand.Material Library Loader is a Blender 4.2+ add-on that auto-builds production-ready PBR materials from any folder of textures — in one click.It understands every naming convention you already use: Substance Painter, Quixel Megascans, Poliigon, Unreal/Unity, custom — and wires up the full Principled BSDF graph for you.WHAT IT DOES• One click → fully wired material: TexCoord → Mapping → Image Textures → Normal Map → Principled BSDF → Output. All correctly connected.• Smart naming detection — recognises 70+ aliases out of the box: BaseColor / Albedo / Diffuse / COL / BC, Normal / NRM / N, Roughness / Rough / RGH / R, Metallic / Metalness / MET / M, AO / Ambient_Occlusion, Height / Displacement, Emission, Opacity / Alpha, Specular / REFL, ORM / RMA / ARM (packed maps), and more.• Bulk mode: point at a parent folder with N sub-folders → get N materials in a single shot. Perfect for importing a Quixel or Megascans library.• UDIM-aware: detects <UDIM> placeholders and .1001. numeric patterns automatically. Image source switched to TILED.• Packed map support: ORM/RMA/ARM splits to the correct Principled inputs.• Glossiness inversion: gloss workflows converted to roughness on the fly.• AO multiply: AO multiplied into Base Color when both are present.• Height handling: choose between true Displacement or a Bump node.• Naming presets: Auto Detect, Substance Painter, Quixel Megascans, Poliigon, Unreal/Unity. Or extend with your own custom suffixes.• Apply to selected: assigns the new material to selected meshes automatically.WHY YOU WANT ITWithout this add-on, every PBR material in Blender takes 5 Image Texture nodes, correct color spaces, a Normal Map node, a Bump or Displacement chain, and 6+ correctly wired Principled inputs. That's 12+ clicks, 5 minutes, every single material.With this add-on: 1 click, 3 seconds.If your project has 20 materials, that's 2 hours saved.COMPATIBLE WITH✓ Blender 4.2 / 4.3 / 4.4 / 4.5 LTS / 5.0 / 5.1✓ Cycles + Eevee (renderer-agnostic)✓ Windows / macOS / Linux✓ All major texture libraries: Quixel Megascans, Poliigon, Substance Source, AmbientCG, Texture Haven, custom setsWHAT YOU GET• material_library_loader-1.0.0.zip — the add-on, ready to install• Full source code (Python)• Extension Platform manifest (Blender 4.2+ Extensions)• Documentation (README + naming reference)• Free updates within the 1.x major versionINSTALL IN 30 SECONDS1. Download the .zip2. Blender → Edit → Preferences → Add-ons → Install...3. Pick the .zip file → enable4. Open the N-panel in 3D Viewport → tab Materials5. Drop a folder of textures → click Load From FolderDone.FAQDoes it work with EXR / TGA / TIFF?Yes. Supported: .png .jpg .jpeg .tif .tiff .tga .exr .hdr .bmp .webp.My naming convention isn't recognised. What now?Open the add-on preferences and add your aliases (comma-separated). Merged into the alias table on every load — no code edits.Can I rebuild a material after editing it?Yes. Re-run the loader and the existing material is wiped and rebuilt from scratch. Slot assignments preserved.Does it support UDIMs?Yes. <UDIM> placeholders and numeric tile patterns (.1001., .1002., …) are detected automatically.Cycles or Eevee?Both. Renderer-agnostic Principled BSDF.Will there be updates?Yes — bug fixes and small features as 1.x updates, free for buyers.License?Single-user commercial license. Use in any number of projects. Don't redistribute the source. Full EULA included.Made by scompa.exe — 3D artist and Blender developer based in Treviso, Italy.
