AwesomeBump

AwesomeBump is a free, open-source desktop tool for turning a single image into a set of PBR material maps. It suits artists and developers who need GPU-assisted texture preparation across Windows, Linux, or macOS without a subscription. Its broad map-generation and conversion toolkit is compelling, but graphics compatibility and an unreliable CMake build make the delivery route important.

Overview

The application generates normal, height, specular, ambient-occlusion, metallic, and roughness textures from one source image. It also works in the other direction: normal maps can become height maps, height maps can become normal maps, and bump information can be extracted from an image. That makes it useful for turning ordinary reference imagery into a workable material set, or for repairing an existing map pipeline.

AwesomeBump is designed around interactive adjustment. Its maker says 99% of image processing runs on the GPU, so parameters can be changed in real time when the graphics hardware meets the requirement. The trade-off is clear: this is a graphics-dependent desktop utility rather than a lightweight, universally compatible converter.

Key features

• Map generation: Creates six common material maps from a single image, giving a practical starting point for PBR workflows.
• Map conversion: Converts normal and height maps in either direction and extracts bump detail, useful when an asset arrives in an inconvenient format.
• Texture tools: Seamless texture creation, perspective transformation, real-time tessellation, material textures, grunge maps, and bump-map mixing cover preparation tasks beyond a single filter.
• GPU editing: Real-time parameter changes can speed iteration, provided the GPU supports the required OpenGL level.
• Saving: PNG, JPG, BMP, and TGA are supported export image formats.

Pricing

The AwesomeBump plan costs free. It is free and open source under the GNU Lesser General Public License version 3 or later, with no paid plans or stated usage limits. That fits hobbyists, students, independent creators, and studios that want a map-generation utility without recurring software cost. There are no paid tiers to unlock additional capacity, so buyers seeking commercial support terms or a tiered service model should look elsewhere.

Platforms

AwesomeBump supports Windows, Linux, and macOS. The README links a version 5.1 Windows package for Windows 7, 8, and 10, version 5.1 for Ubuntu 18, and version 5.0 for Ubuntu 14. Source builds are intended for platforms supported by Qt and include a Unix build script, but the README warns that the current CMake script does not work. Build instructions require a graphics card supporting at least OpenGL 4.0; an OpenGL 3.3 build exists, though tessellation is unavailable there.

Who it's for

Choose AwesomeBump when you need desktop-based material-map generation, conversion, and texture cleanup in one free tool, especially for a PBR pipeline where interactive GPU adjustment matters. It is less suitable when your hardware cannot meet OpenGL 4.0, when tessellation is central to the workflow, or when you need a polished installer and dependable source-build process.

Pros and cons

Pros

• Generates a complete set of widely used PBR maps from one image.
• GPU-heavy processing and real-time controls support fast visual iteration.
• Includes conversion, seamless-texture, grunge, tessellation, and bump-mixing tools rather than only map baking.
• Free, open-source licensing removes subscription and usage-limit concerns.
• Runs on Windows, Linux, and macOS, with common PNG, JPG, BMP, and TGA exports.

Cons

• OpenGL 4.0 is required for the main build, and the OpenGL 3.3 option loses tessellation.
• The current CMake script does not work, complicating source compilation.
• Published download targets are older Windows and Ubuntu versions, so newer systems may require a source-build route.

Alternatives

For a broader starting point, browse 3D Texturing Software or Game Texture Software.

• Mixos Paint is the better fit for a cross-platform, browser-inclusive workflow, but its free plan has 100 MB of cloud storage, 10 trial AI credits, a 512px 2D texture view cap, and export restrictions.
• Surface Labs suits users wanting a free early-access product across mobile, desktop, and API environments.
• InstaMAT is an alternative for users who qualify for its free Pioneer License, which covers Windows, macOS, and Linux with attribution required.
• Marmoset Viewer is appropriate when the need is viewing rather than generating maps; its free standalone Viewer is included with Toolbag versions 2.07 and newer.
• Trumble offers browser-based access and a free tier with current and future tools, but includes workspace ads.
• LigidPainter is another completely free Windows, Linux, and macOS option, listed as name-your-own-price.
• Mari has a free non-commercial plan, with exports limited to 4K and 16-bit per channel and Python scripting disabled.
• Material Maker provides a name-your-own-price desktop download under MIT code and CC0 asset licensing; its Steam edition costs 14.99 USD once.

Verdict

AwesomeBump is a strong choice for anyone who wants a no-cost, open-source way to generate and reshape PBR maps on the desktop. Its main reason to choose it is the unusually broad texture toolkit paired with GPU-driven, real-time adjustment. Look elsewhere if your machine misses the OpenGL requirement, you depend on tessellation with older hardware, or you need a smoother, currently maintained build-and-install experience.
