Bas Relief from texture (not enough)

[Box5]

Thanks for the fast reply. I think I have to give up on the bas relief technique and go with a displace modifier in 3ds. I got it spot on with that, now i'm having a hell of a time importing it to ac3d in the correct scale. I need it spot on, otherwise the roads I make will be way off. 3ds meters turn out to be gigantic in ac3d.... I guess i'll just do trial and error with my current roads and find a number that seems right. Thanks again for the help.
