How do I export the normals for mesh geometry when I Export to Wavefront OBJ format?

If it's not possible in Lightwave to export the normal data, what tool(s) should I use to generate the normals so they are exported when I export to an OBJ file?

Maybe the program thats reading the obj file has the normals flipped. I can't see any reason why you would not see the normals, other than then being flipped.

UV Mapper Classic ( www.uvmapper.com ) includes an option to export normals, if they really aren't in the OBJ file to start with (it works them out from the winding order, but most things that read OBJ files should do that themselves).
