.alr — Allegorithmic Image File
Allegorithmic · 2014
.alr files are project files from Allegorithmic's Substance Painter, used for storing 3D painting and texturing data.
Key Features
- Stores comprehensive 3D painting project data.
- Includes texture maps, layers, and material settings.
- Enables non-destructive editing of 3D assets.
- Proprietary format for Allegorithmic/Adobe Substance Painter.
Best For
- Maintaining complete project history in Substance Painter.
- Iterative development of 3D textures.
- Collaborative 3D art projects using Substance workflow.
- Preserving intricate layer stacks and material definitions.
Less Ideal For
- Directly displaying images on websites or in galleries.
- Sharing with users who don't have Substance Painter installed.
- Using as a general-purpose image format for print or web.
- Embedding into documents or presentations as static images.
Common Use Cases
- Saving ongoing 3D texturing projects in Substance Painter.
- Archiving finished Substance Painter projects for later revisions.
- Sharing project files between different artists working on the same 3D model.
- Backing up complex 3D painting work.
How to Open It
- Open .alr files directly within Adobe Substance Painter.
- Ensure you have a licensed version of Substance Painter installed.
- If collaborating, share the .alr file and any associated texture maps.
- Export textures from the .alr project to other formats (like PNG, TGA) for wider use.
What is a .alr file?
The .alr file extension is associated with Substance Painter, a powerful 3D painting software. It is not a standard image format like JPG or PNG, but rather a proprietary format used internally by Allegorithmic's (now Adobe) software. These files typically store information related to 3D texturing and painting projects, including texture maps, material settings, and painting layers. They are crucial for preserving the detailed work done within Substance Painter and allow for further editing and iteration of 3D models. While not directly viewable as a typical image, they are vital for the 3D art pipeline.

Common Problems with .alr Files
Frequently Asked Questions
No, .alr files are project files for Substance Painter and cannot be opened directly in Photoshop. You would export textures from Substance Painter to formats like PNG or JPG to use them in Photoshop.
.spp is another project file format for Substance Painter, often used for older versions or specific project types. .alr is more commonly associated with Substance Painter's primary project file structure for 3D painting.
No, .alr files are not standard image files. They are project files that contain the data necessary to render 3D textures and materials within Substance Painter.
Technical Details
ALR files are binary files that serve as containers for project data in Substance Painter. They encapsulate information like diffuse, normal, and roughness maps, as well as brush strokes, layer information, and material presets. This structure allows for non-destructive editing and complex material layering within the 3D painting environment.
