Why we like it

Atlasflow earns its place in the superhive library for handling per-face PBR variation through UV maps rather than heavy texture sets, keeping material management light and glTF export straightforward.

What is Atlasflow - Ultimate Color Atlasing?

Atlasflow enables per-face PBR editing inside a single material, using two lightweight 128×128 pixel textures under 16kb and up to four UV channels. Through a UV manipulation system you edit colors and PBR properties for individual faces or groups of faces, reaching over 72 quadrillion PBR value combinations. An entire scene can be composed of one material without losing editing capabilities, which cuts draw calls and simplifies material management. That makes it suited to game asset creation, stylized models, or any project demanding high optimization or fast-paced production.

Rather than relying on complicated shader nodes or custom data, Atlasflow manipulates UV maps to achieve the look, so results are glTF 2.0 (.glb/.gltf) export-ready. It is ready for direct integration with glTF-compatible frameworks such as Babylon.js, WebGL applications, VR/AR projects, Unity, or any platform that supports .glb.

Adding an Atlasflow material creates UV channels and automatically captures the existing materials' default PBR values, transferring them to the matching channels while keeping the originals intact. Editing works much like a traditional PBR material, but per-face, with shader node and UV handling taken care of behind the scenes.

Frequently asked questions

How do I install Atlasflow - Ultimate Color Atlasing in Blender?

Atlasflow - Ultimate Color Atlasing installs like any standard Blender add-on. Download the Atlasflow .zip file, then open Blender and go to Edit > Preferences > Add-ons > Install from Disk to load it. From there you select a mesh object and click Add Atlasflow Material to begin. That operation also creates UV channels and automatically captures the object's existing default PBR values, transferring them to the corresponding UV channels so the model keeps its original look. Your original materials and UV channels stay in place if you still need them.

Does Atlasflow export to glTF for Unity or Babylon.js?

Atlasflow - Ultimate Color Atlasing is built for glTF 2.0 export, producing .glb and .gltf output. Rather than relying on complicated shader nodes or custom data, it manipulates UV maps to achieve the look, which keeps results portable. That makes it ready for direct integration with glTF-compatible rendering frameworks, including Babylon.js, WebGL applications, VR and AR projects, Unity, or any platform that supports .glb. If your pipeline targets one of those, the material carries over for direct integration.

What PBR properties can Atlasflow edit per face?

Atlasflow - Ultimate Color Atlasing works with Color and Gray atlas types, and you can combine up to four atlas textures in a single material. Color atlases cover Base Color, Emission Color, Specular Tint, Sheen Tint, and Coat Tint. Gray atlases cover Metallic, Roughness, Alpha, Specular IOR Level, Transmission Weight, Coat Weight, Coat Roughness, Sheen Weight, and Sheen Roughness. By default the add-on uses Base Color, Metallic, and Roughness. In Edit Mode you can adjust these property values per face or group of faces.

What happens to my existing materials when I add an Atlasflow material?

Atlasflow - Ultimate Color Atlasing keeps your existing setup intact when you add a material. Clicking Add Atlasflow Material creates the needed UV channels and automatically captures the default PBR values from the object's current materials, transferring them to the matching UV channels so the model retains its original look. Both the original materials and original UV channels are preserved in case you still want them. If you'd rather strip that data from the model, the Clean operation removes it.

Is Atlasflow - Ultimate Color Atlasing free?

Atlasflow - Ultimate Color Atlasing is listed as free in this catalog. Because licensing terms and any future pricing can change, it's worth checking Baltha Studio's page on superhive for the current details before you download. The add-on ships with documentation to help you get started, and installation follows the standard Blender add-on process through Edit > Preferences > Add-ons > Install from Disk. A demo video is also available if you want to see more first.
