AwesomeBump is an open source program designed to generate normal, height, specular or ambient occlusion textures from a single image. Since the image processing is done in 99% on GPU the program runs very fast and all the parameters can be changed in real time.

PixPlant is a smart texturing app with the best tools to quickly transform a photo into seamless repeating textures and 3D maps.

This tool lets you generate normal maps for 2D textures, with little effort. Specially designed for Sprites in 2D games.

Quixel was founded in 2011 by Teddy Bergsman and Waqar Azim, based on the vision of substantially speeding up how creators build digital environments, by giving them access to a vast and ever-expanding library of 3D building blocks, and easy-to-use tools to greatly simplify the...

Materialize is a stand alone tool for creating materials for use in games from images. You can create an entire material from a single image or import the textures you have and generate the textures you need.

xNormal is an application to generate normal / ambient occlusion / displacement maps. It can also project the texture of the highpoly model into the lowpoly mesh ( complete texture transfer, even with different topologies ).

Sprite Lamp is a software tool to help game developers combine 2D art with dynamic lighting effects, through the creation of hand drawn normal maps.

This is a suite of ten Gimp plugins known as the 'Resynthesizer'. The most commonly used is 'Heal selection' but all use the plugin whose full interface is found at 'Filters>Map>Resynthesize.

ModLab is a free tool that can generate and fine tune normal maps in a realtime rendering environment.

SpriteIlluminator lets you easily generate normal maps for your 2d game and web projects. Render dynamic lighting & other effects and use paint tools to directly draw on the normal map and fine tune the effects.

Converts a bitmap into a seamless PBR material, including normal, AO, roughness and metallic.

Njob is a simple tool that supports a number of filters related to normalmapping and texture creation. I’ts key design philosophies are:
