Hello there! Introducing NormalPainter, an image editor I made for handpainting normal maps. You can control which normal direction you want to paint by pointing your joystick or graphical tablet pen in the correct direction. This makes it much easier to pain normal maps instead of having to sample the direction everytime. There is other features such as pinning which let’s you choose the direction with even less work. Check the video for a quick showcase:

It sure is a very specialized software. Handpainting normal maps is not something you have to do in most scenarios (generating them is often more convenient). If you are looking to make a 2D cartoonish game with dynamic lighting (like mine!) I think it’s very useful. At least it was useful to us in the development of our last big update.
The software is entirely free and open source.
