FBX is something that has plug-ins for both 3DSMax *and* Lightwave, thus making converting from one format to another much easier.

Kaydara FBX or Filmbox format, now Alias FBX, is a file format that allows exchanging 3D objects and animations between 3D apps. It can work well, but also produces some unexpected results from time to time.

It is quite useful. You can find out more about it here:
