I've contacted Dave Wyand about the possibility of keeping credit instead of assigning all copyright to GG. That would probably mean changing the OSA agreement. Incidentally, I've actually done
just that when I imported a library to go with googletest. I asked GG about that and from what I remember, the answer was 'sure whatever'. The whole status of contributions (which are marked MIT and (c) GG) and libraries (many of which we have included in lib/ as source) is unclear to me. What's to stop us putting Andrew's code in lib/, keeping the same copyright, and using it?
The flipside of the coin is that I and a couple of other SC members want to see T3D becoming more 'distributed', so that improving the engine is less a question of pulling every single thing we can find into the main repo, but instead providing easy ways for users to discover addons, pull them down, integrate them, and rate them. That way Andrew can keep his code, and users can get it without it having to be in the core engine.
Finally, I personally feel that deferred shading is the way the engine will head, anyway, so porting LPV back to deferred lighting will become redundant in the future. Who knows how far that will be, but hopefully within the year.
Also, thanks for the kind words about Walkabout, Andrew
