Why we like it

Atlas earns its place for handling the fiddly parts of atlasing: it rotates normal map vectors correctly to avoid seam artifacts on repositioned assets, and applies color bleed on all channels so transparent areas are filled rather than left with black fringing.

What is Foliagelab - Atlas?

Foliagelab - Atlas is a Blender add-on built around a simple flow: point it at a source folder of PBR textures, and it scans, detects assets by filename convention, and places them in scene ready to arrange and bake. Detection needs no manual setup, and it auto-detects each asset's size (Big, Medium or Small) from filename keywords, adjustable manually when needed. A wide range of naming conventions is supported out of the box, including _BaseColor, _BC, _Diffuse, _NRM, _Roughness, _Gloss, _Mask, _AO and _Subsurface.

Single-element textures are treated as squares, while multi-element textures get a convex hull based on pixel distance. Assets are placed by size, you can lock individual sizes before redistributing, and automatic rotation can be toggled to maximize packing efficiency. Padding and overlap are adjustable per placement pass, and a full PBR viewport preview lets you switch between Albedo, Normal, Roughness, AO and Opacity.

All PBR channels export as separate atlas files, baked outside Blender through an independent pipeline, no render required. It also offers custom channel packing, color bleed on all channels, normal green-channel inversion for DirectX/UE5, and PNG, TGA, TIFF or EXR output up to 16K. Requires a flat folder structure and Blender 4.2+.

Who is Foliagelab - Atlas best for?

Foliagelab - Atlas is best for blender artists building texture atlases from PBR foliage and vegetation assets for game-art and real-time pipelines.

How much does Foliagelab - Atlas cost?

Frequently asked questions

Does Foliagelab - Atlas work with Blender 4.5?

Foliagelab - Atlas supports Blender versions 4.2 through 4.5, with 4.2 listed as the minimum requirement. It's distributed as a Blender add-on, published as an extension. If your Blender falls in the 4.2 to 4.5 range, you can install it and start scanning a folder of PBR textures for atlasing. For newer or older Blender releases outside that supported range, check the developer's page to confirm current compatibility before installing.

What folder structure does Foliagelab - Atlas need?

Foliagelab - Atlas requires a flat folder structure. You point it at a source folder containing your PBR textures, and it scans that folder to detect assets automatically by filename convention. It recognizes a wide range of naming conventions out of the box, including _BaseColor, _BC, _Diffuse, _NRM, _Roughness, _Gloss, _Mask, _AO and _Subsurface, among others. Because detection runs on filenames, no manual setup is needed to get assets recognized and placed in the scene.

What formats and resolutions can Foliagelab - Atlas export?

Foliagelab - Atlas exports all PBR channels as separate atlas files, baked outside Blender through an independent pipeline that needs no render. Output formats include PNG, TGA, TIFF and EXR, at resolutions up to 16K. It also supports custom channel packing per preset, such as ORM, can bake opacity into the Albedo alpha channel, and applies color bleed on all channels so transparent areas are filled to avoid black fringing at texture borders.

Does Foliagelab - Atlas handle normal maps for UE5?

Foliagelab - Atlas can invert the normal map green channel for DirectX and UE5 workflows, offered as an optional toggle. It also rotates normal map vectors correctly within the atlas, so repositioned or rotated assets don't produce normal seam artifacts. Additional export options include glossiness to roughness inversion, applied per asset or globally, and a Subsurface / Translucency channel that's detected and exported alongside the standard PBR maps.

Is Foliagelab - Atlas free?

Foliagelab - Atlas is listed as free in this catalog. Licensing and pricing can change over time, so for the current terms it's best to check the developer's page directly. The add-on is distributed under the GPL license as a Blender extension. If you plan to use it in a production or commercial pipeline, reviewing the license on the developer's page will confirm exactly what's permitted.
