Lightwave isn't hard to learn... and if you aren't selling any of the graphics, I don't see why downloading it off the net would be a problem (unless you have dial-up lol). I won't post any links or anything since even downloading it is illegal.
There are countless lightwave tutorials on the net, they're easy to find too. Just type "Lightwave Tutorial" at yahoo or google... or some other search engine.
Personally I've only experimented with it in small ways, not nearly enough to make graphics for a plugin, though from what I've seen, I won't have much of a choice since no one has applied for my Wing Commander development team. Some might say I need to prove that it won't become vaporware so I guess I can understand. Though I won't let it be... even if I have to buy a mac and do it all myself and have it done in time for 2010... 
Until then, I'm patiently waiting for a windows editor to come out. I've heard of no actual editor yet and I won't ask since this topic has already answered that question.
Thank you for your time.
