the OpenFlight loader does not support "text" records. This is noted in
the OpenFlight pf loader README file
/usr/share/Performer/src/lib/libpfdb/libpfflt/README.FLT.R15_3, see
below:
<snip>
----------------------------------------------------------
| MultiGen OpenFlight features NOT supported |
----------------------------------------------------------
- header attributes are ignored, except:
- format revision
- database units
- projection type
- text beads are ignored
^^^^^^^^^^^^^^^^^^^^^^^^
- linestyle palette is ignored
<snip>
You will have to make your text normal geometry (polygon) nodes. I'm not
quite sure how you do that though. Hope this helps.
