This is available in github<br>

“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)
