The LightWave Manual doesn't appear to have been updated since 2013. It says 2017, but most of it is older. Almost all images of nodes are missing many "pins" and other elements that have been introduced in the intervening years.
There is nothing about Spectron & Vectron. Many other new plugin features are absent. I'm regularly having to read the standalone manual to find out how stuff works but trying to interpolate that information into LightWave is often hopeless.
I also have trouble searching the LightWave subforum. Most search results, both local and on google, are for standalone version or other plugins. This is all very frustrating.
