QUESTION Interior AO texture

[Fuzo]

Guys could someone help me with interior AO texture? I am creating scratch made model and following the Kunos pipeline but I can't figure out how to use baked AO texture for interior. I managed to bake AO in 3dsmax (saved as PNG) but I am not sure which format to use when saving it in Photoshop (or directly in 3dsmax). Pipeline suggests DDS 8.8 (alpha/luminance) but when I use it the whole interior looks white as the texture. When I try to check Kunos textures, theirs AO texture does not have alpha channel, but when I save my interior AO as 8.8 in Photoshop, it creates alpha and the result in ksEditor is very different. Any leads someone?

What are your shader settings? White could mean it just has Spec at 1.0 as the Editor does for new materials for whatever reason.
There is no format it needs to be to work, PNG or even JPEG is fine, tho you want DDS (any of the variants, I mostly use DXT5 when I have an extra detail texture or just simple DXT1 if I don't) for the final release as it offers best performance.
