All of the above is of course extremely obvious, and
it is not because I haven't thought of all that
myself, but once again is all because of the
unfinished state of the (quickly thrown together)
patch. It was kind of surprising actually to see the
'NMap TS' button still in the same place, I would have
thought that would at least have been modified.
There was some reason I did put it temporarily in the
material button section, but can't quite remember why
that was anymore (created patch sometime earlier this
Sorry for all this, but as I said before, I didn't
really think the patch was going to be integrated as
is without modification.

I was hoping that renderdemon was going to take it up
from here, but I think he has given up on it
unfortunately, from what I can understand at least on
the Italian kino3d forum...
