(Oh, there's more info here, I also replied on Steam)
p_attonbb is for the body.
The head needs P_AttnH1, P_AttnH1D1 and P_AttnH1D2.
But.. in kotor 2 the "D2" is max dark side, in K1 just "D" is max dark side.
In K1 the order is: no D, D1, D2, D3, D.
So in K1 there's 2 more states. In an image editor you can make textures for those in between states by doing a 50% opacity mix of a layer above another layer.
