Donna PBR automates the full PBR texture export pipeline directly from your Blender shader nodes — in one click.

Stop exporting textures one by one. Stop manually packing channels, inverting Smoothness, or flipping Normal maps for each engine. Donna PBR handles all of it automatically.

ENGINE PRESETS

→ Unreal Engine 5 — ORM map (R=AO G=Rough B=Metal), DirectX normals
→ Unity (Metallic/Smooth) — MRa map, automatic Smoothness inversion
→ Unity HDRP — Mask Map (R=Metal G=AO B=0 A=Smooth)
→ Godot 4 — ORM layout
→ glTF 2.0 — Blender glTF exporter-compatible suffixes
→ Marmoset Toolbag — DirectX normals, separate maps
→ RMA / O3DE — RMa layout
→ PBR Standard — separate Roughness + Metallic
→ Custom — fully configurable, saveable as preset

KEY FEATURES

◆ One-click export — Roughness, Metallic, AO, Albedo, Normal, Height, Opacity, Emissive, Specular

◆ Texture Auto-Detection — walks the Principled BSDF node graph and auto-fills all slots. Supports complex setups (MIX nodes, SEPARATE_COLOR, GROUP inputs). Confidence scoring included.

◆ Batch Export — all materials from all selected objects in one pass. Each material gets its own subfolder. Blender stays fully responsive.

◆ UDIM — full tile support across all map types.

◆ NumPy Pipeline — ~10× faster than pure Python on 4K+ textures. 4096×4096 in under 1 second.

◆ Check Scene — dry-run validator: scan every material in the scene and get OK / WARNING per material — without writing a single file.

◆ Export Queue — queue multiple jobs and run them sequentially.

◆ Headless CLI — export from the command line, no UI required. Perfect for CI/CD pipelines.

◆ Public API & Plugin Registry — third-party addons can register custom map types and presets without forking the source.

◆ 10 UI Languages — EN, IT, ES, FR, DE, ZH_CN, ZH_TW, RU, JA, KO.
