“Normal Map Maker” - Simple editor plugin for creating normal(bump) maps from textures.
* This is not “super quality” normal map generator, there are professional tools for that. Rather it is a “poor man’s” tool for testing.

** Note. Specular map is created as a separate texture.

FEATURES
- Create normal(bump) map from any texture
- Adjustable bumpiness strength
- Median filter with adjustable size
- Basic specular map creation also included
- Adjustable brightness cutoff
- Adjustable specular contrast
- Progress bar with cancel button
- Automatically set [x] Read/Write enabled for source texture (for temporarily)
- Automatically set created texture “ Texture type: Normal Map”
- Textures are created to the same folder as the source with added suffix “_normal” or “_specular”
- C# source (inside custom namespace)

NEW 1.2
- Runtime version (create normal, specular maps and filtering at runtime)
- Runtime demo scene added (loads texture from web, creates normal, specular & uses filter)
- Runtime public methods: NormalMapTools.CreateNormalmap(), NormalMapTools.CreateSpecular(), NormalMapTools.FilterMedian(), NormalMapTools.CombineRGBAndSpecular()
- Added 3 custom shaders (for using runtime made normal maps, because cannot use UnpackNormal() in shaders for those)
