Yes. The standard 'advanced terrain pack' is part of the SDK. I assume that the truly advanced version will be released at the same time that Mike eventually releases the DBPro version.
Quote: "how stable is the network code you are writing?"
Very. I haven't had any problems with the core network code for a long while now. Pretty much everything that can be checked is checked. Despite that, it's still fast. It's all based on winsock, not directplay (why reinvent TGC's wheel), and allows either TCP or UDP connections.
There is no prediction included, simply because I can't cover even a fraction of everyones needs, data formats, dropped packets etc. There is also no masking included, again because only your application can decide whether a client needs to be updated again.
No price at this point - I plan to be guided by someone with a little more knowledge on that than I have.
