AMBIENT_OCCLUSION

Greetings

There is a file name : mi_8_tex_1_ao which is controlling the Red channel (Ambient Occlusion ) , adding shadows behind armor plates on nose or in some other areas !!!
my question is how that thing works properly ?!

thanks

Im no expert but from what i understand it is a grayscale image to control the stregth of the shadow that gets casted onto the texture.

The file consits of four images the last two are without the shadow casted by the armor.

If you want to remove that shadow for example you would need to copy one of the last two images over the first two images.

Iirc. i saw that trick first inside a livery by Eight Ball.

The file is a *.dds (DirectDrawSuface) there are several free programs that are able to work with these files.

Many thanks for your answer ! I know about PBR and how is working !
but my question is :
does it mean i have to copy it in Roughmet Red channel ?! or is that file works independently ?! if yes how should i edit the description file in liveries folder !?!

I only needed to modify the AO file to get rid of the unwanted shadows. 

Put the modified AO texture inside your livery folder and add this line to the description lua:

{"mi_8_tex1", AMBIENT_OCCLUSION	, "mi_8_tex_1_ao", false};
