I updated the book in the last few days to include some of the Max objects that automatically export as entities in Max. For example, an Omni light exports as a light entity, a Target Spot as a light_spot with an info_target, etc.
I also want to point out there was a critical bug in a version of WW posted last week. If you happen to use WW and Max crashes when you open the WW menu after last week's update, here is the fix. Don't ask me what ju-ju is the culprit... all I know is how to fix it.
Also, I've added a new commercial plugin: Carver + Make Hollow
