Why we like it

Atlas Pro earns its place in the Superhive library for handling atlasing across multi-material production assets, deduplicating shared materials, and writing engine-ready PBR output in a single command.

What is Atlas Pro?

Atlas Pro is a Blender add-on by Skava for building texture atlases from production scenes. Select your meshes, pick a resolution, and click Create PBR Atlas: the tool walks every material slot of every selected object, dedupes identical materials, packs source textures into a single unified atlas per map type (Albedo, Normal, ORM, Emission), rewrites the UVs of each face to fit its tile, builds a single Principled BSDF material, and assigns it to every object.

It reads Base Color, Normal, Roughness, Metallic, AO and Emission from every material slot and builds packed atlases at 512, 1K, 2K or 4K, with an optional ORM combined map (R=AO, G=Roughness, B=Metallic). A recursive node-chain walk finds the source Image Texture through up to 8 levels of intermediate nodes. Original material lists are stored in a custom property before replacement, so the change is reversible.

Beyond PBR atlases, Atlas Pro builds trim sheets in horizontal, vertical or grid layouts, generates palette textures from dominant colours, offers LOD-aware atlas allocation, and includes a standalone Channel Pack with ORM, Unity Standard, Unreal ORM and Mobile Compact presets.

Who is Atlas Pro best for?

Atlas Pro is best for game artists shipping to Unity, Unreal or Godot, environment artists on open-world, mobile or VR projects, hard-surface modellers using trim sheets, indie developers, and tech artists building automated content pipelines.

How much does Atlas Pro cost?

Atlas Pro is completely free to download and use.

Key features

  • PBR Atlas Builder: a single command reads Base Color, Normal, Roughness, Metallic, AO and Emission, builds packed atlases at 512/1K/2K/4K plus an optional ORM combined map, and rewrites UVs per-face
  • Multi-material per object plus deduplication: reads every material slot of each object, and merges identical materials referenced across the selection into one atlas tile
  • Save to disk with a naming template supporting {name}, {map} and {res} tokens, writing atlas images as PNG to a chosen output folder
  • Trim sheets built from selected materials in horizontal, vertical or grid layouts for modular kits
  • Palette textures: generate an N×1 palette image (4, 8, 16 or 32 colours) from dominant colours, collapsing each face's UV onto its colour pixel
  • LOD-aware atlas allocation, sizing space proportional to LOD level from LOD0 down to LOD3
  • Channel Pack standalone packer with built-in ORM, Unity Standard, Unreal ORM and Mobile Compact presets

Frequently asked questions

Which Blender versions does Atlas Pro support?

Atlas Pro supports Blender 3.0 through 4.5 and later. It runs from the N-panel: open the AtlasPro tab, go to the PBR Atlas panel, select your meshes in the viewport, set the resolution, tick the maps you want, and click Create PBR Atlas. A progress cursor shows the percentage, and on completion the info bar reports materials processed, objects touched, and draw calls saved. The atlas data is engine-agnostic, so it works with any render engine.

Can Atlas Pro handle objects with multiple material slots?

Atlas Pro reads every material slot of each selected object and emits a tile per material, so production assets such as clothes, vehicles and characters with three to ten materials per object are handled. This behaviour can be toggled off to revert to active-slot-only processing. Identical materials referenced multiple times across the selection are merged into one atlas tile, producing a tighter atlas and larger draw-call savings. A recursive node-chain walk finds the source Image Texture through up to eight levels of intermediate nodes.

Is the material replacement in Atlas Pro reversible?

Atlas Pro stores the original material lists in a custom property before replacement, so the change is reversible. When you re-run the tool, the existing atlas material is reused rather than creating duplicates like Atlas.001 and Atlas.002, keeping the file clean. The ORM atlas's red channel is multiplied into Base Color so ambient occlusion contributes to shading. You can also set an output folder to write each atlas image to disk as PNG using a custom naming template.

Is Atlas Pro free to use?

Atlas Pro is listed as free in this catalog. For current licensing terms and any conditions on commercial use, check the developer's page. The tool is a Blender add-on that works with any render engine, since the atlas data is engine-agnostic, and it targets pipelines shipping to Unity, Unreal, Godot and glTF through its configurable naming tokens. Its Channel Pack also ships with ORM, Unity Standard, Unreal ORM and Mobile Compact presets for packed RGBA output.
