Are you sure? It reduces the vertex count by a full factor of two. For a single tree, that's a savings of 12 vertices; immesurable noise for a single tree, but for a forest of thousands? I could easily see us running into GPU throughput issues with this. It's probably not something to worry about for a good while, though. As David points out, it can't be done without hacking plib's internals. Andy -- Andrew J.
