Ventilator: Thank you. That sounds interesting. The blender tool simply uses the ATI normal mapper that I mentioned above (with the strange .nmf - Format that I do not know). But it has the advantage of better import and export options through blender.
I did another search and found a nice tool called O.R.B. that seems to use the normal map generator from the doom3 team. That supports 3 file formats and native Lightwave files:
