in A8 that's spec_bump.fx !
But soryy, it's not normal map and specular map.
Caus there is a specular parameter, is just a spacular value applied to all mesh , not with a specular map.

I'll try to search on Acknex Unlimited and some shader packages
if i can find one.

I'm very surprised A8 have not that very standard, and very used shader ??
