This is a script that updates all texturepaths in an array of maxfiles

/*
IMPORTANT to know... this ONLY works on maxfiles 
SAVED with 3dsmax 2010 or newer.. Older maxfiles 
will just return an empty array...

solution is to open an old maxfile in a new version 
of max, and save it from the newer max

--This is a small function that updates the texture path
fn UpdateTexturePath filename newTexturePath = (
  --Get all fileAssets in a maxfile and store in an array
  fileAssets = getMAXFileAssetMetadata filename

  for fa in fileAssets do ( 

--for every fa get just the filename and filetype..
  fname = (getfilenamefile fa.filename + getfilenametype fa.filename)

--Update the old texturePath with newTexturePath + old filename
  fa.filename = newTexturePath + fname

--this write the information back to the file
