What can AwesomeBump do?
convert from normal map to height map,
convert from height map (bump map) to normal map,
extract the bump from the arbitrary image,
calculate ambient occlusion and specularity of image.
perspective tranformation of the image,
creating seamless texture (simple linear filter, random mode, or mirror filter),
generate roughness and metallic textures (different types of surface analysis are available),
real time tessellation is available,
saving images to following formats: PNG, JPG,BMP,TGA
edit one texture which contains different materials
add some grunge to your map with grunge texture.
mix two bumpmaps togheter with normal map mixer.

Atlas generation tool This tool performs mesh segmentation, surface parameterization, and chart packing. This is especially useful when generating light maps for meshes that do not have artist-supplied uv's. https://github.com/Thekla/thekla_atlas
"Boundary First Flattening (BFF) is a free and open source application for surface parameterization. Unlike other tools for UV mapping, BFF allows free-form editing of the flattened mesh, providing users direct control over the shape of the flattened domain—rather than being stuck with whatever the algorithm provides. The initial flattening is fully automatic, with distortion mathematically guaranteed to be as low or lower than any other conformal mapping tool. The tool also provides some state-of-the art flattening techniques not available in standard UV mapping software such as cone singularities, which can dramatically reduce area distortion, and seamless maps, which help eliminate artifacts by ensuring identical texture resolution across all cuts. BFF is highly optimized, allowing interactive editing of meshes with millions of triangles." https://github.com/GeometryCollective/boundary-first-flattening

Insane Bump can generate the following texture maps:
Normal Maps: Rich vivid normal maps with a wide spectrum of detail sizes analysed
Ambient occlusion maps: fake AO maps to shade crevices in the texture draker
The AO map is saved in the alpha channel of the normal map
Height map
Specular Map
