is it possible to get hammer to recalculate the displacement normals?

[adamspurgin]

let's say i wanted to manually alter/create a .vmf with a singular displacement inside. i would love it if i could just deal with the distances and let hammer take care of the rest. is there a sort of "refresh normals" function?

i'm working on a program to import z-maps into displacements (there isn't one already, is there?) and the only thing keeping me from getting anywhere is the normal calculations.

i guess that's a resounding "i don't know"
