just checked that out and, by applying the filter twice after each vector
creation it works now. That has completely caught me out. I assumed (not a good
thing clearly) that the filter would transform the entire data-set, but at least
it explains why only a single vector was getting converted to a
float.</FONT></SPAN></DIV>

<P>When you use the transform filter it will also transform the "active"
vectors, i.e. rotating the model will rotate the vectors too. Note: this
is very confusing if you have multiple vectors as it is not immediately obvious
which one is getting transformed (as only one is "active").
