Sadly, Lightwave doesn't have a Mac version. I may goof around with the trial in Windows, anyway... all of my art software is Mac, though, so setting up a workflow would be awful. Blenders' curves work by essentially pasting in a generic curve which must be modified into the shape you want. This is no way to create curves. Maya's are a little better, but as far as I can tell, are missing little things which make Illustrator's beziers so nice... like holding shift to force a 90 degree handle and fast ways to chop a handle off. Maybe those commands are in there somewhere, but I haven't found them. It's also expensive, of course.
