Yes, I'm sorry, I just don't know quite how to apply it to the HF:
This doesn't work:

height_field {
 tga concat("fig", str(clock*100,-2,0), ".tga")
 smooth
 scale <1,-1,1>
 translate y
}

nor does this:
height_field {
concat("fig", str(clock*100,-2,0), ".tga")
 smooth
 scale <1,-1,1>
 translate y
}

Could you show me the line in this context?

thanks again,
Dennis
