Thats great, thanks! works very well!! REALLY appreciate the contribution.
can it use level ambient color in the future? also, point light and/or object light sources would be great.. then ill work on a flashlight effecct, hopefully the light source could be attached, moving a specular over the objects...I did it with the older dx8 normal map code, but the light would get stuck on an ebject...
Thanks again!

I'm glad it works well for you . I'm gonna look into the ambient lighting as well as work on those object lightsources.
