Laigter is described as 'This tool lets you generate normal maps for 2D textures, with little effort. Specially designed for Sprites in 2D games' and is an app in the Development category. There are more than 10 alternatives to Laigter for Windows, Mac, Linux and Python. The best alternative is AwesomeBump, which is both free and Open Source. Other great apps like Laigter are Quixel Suite (Freemium), Crazybump (Paid), NVIDIA Melody (Free) and Substance B2M (Paid).
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.
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...
NVIDIA Melody creates high quality normal maps that make a low-poly model look like a high-poly model. Simply load your low-poly working model, then load your high-poly reference model, click the "Generate Normal Map" button and watch Melody go to town.
Njob is a simple tool that supports a number of filters related to normalmapping and texture creation. I’ts key design philosophies are: Intelligent filters that make your life, creating game textures, easier.
Unflattener is a free and open source Python module and a command line tool (unflatten.py) that helps you make normal maps for 2D sprites and other graphics. You can use the normal maps it generates to implement dynamic lighting in video games.
