@Liranius
Wow, This is ...... wrong. What the transformation such as the puzzle.
Correct:http://i.imgur.com/O6YQEb5.png
There may be the problem with your computer or software(Photoshop ver?).

I recommend you try different softwares.(e.g. Paint.net , GIMP, )

@stmSantana
This is the original aci.png: http://postimg.org/image/or0i0xuqx/
This is the split B channel: http://postimg.org/image/vwwuh4t7t/
This is the result after using Tone Curve Tool: http://postimg.org/image/u3pcf2ind/

Infact, any modification I made to the generated greyscale images will cause a distortion. I don't know if I have done something wrong, or there are something wrong with my photoshop or computer.

Hi @Liranius, Thanks for reading this guide.
What is a strange thing? If it’s possible, Please show me your Screenshots.

When the Asset-Importer imports textures, it invert lightness of 3 images (alpha mask, color mask, specular).
At the same time, it changes lightness of all images.

So, What you should do is follows,
1. Separate channel and get grayscale images.
2. Ctrl+M (Tone curve tool) to darken curve a little. (chapter "Brightness ,Invert, Tone curve")
(However, AlphaMask_a & ColorMask_c use only 2 colors, black/white, Consequently you don't need to do this step.)
(If you edit vehicle textures, You should read instructions of Edit-Illumination row)
(If you edit building textures, You should read a chapter "Comparison")
3. Ctrl+I to imvert images (only _a, _c, _s)
4. Export images.

Sorry for bothering you. I don't quite understand what does Invert and Edit rows in your picture mean. I executed separate channels to an xxx_aci.png in photoshop and get 4 grayscale images. Then I executed Ctri+I to invert the image. Then I exported images but got something strange. Which step is wrong? Or was I missed some steps?
