Am beginning to get the idea that a 1,000,000 Watt Arc-Lamp wouldn't illuminate the topic any further, I'm afraid. I've just had a look around, niiice game btw, and all I could find were installation instructions, a couple of posts in a forum somewhere, in which somebody suggested the use of IL-2 models in his own game, and got flamed and no help for it. Additionally, a small exerpt in a home-brew flightsimulator page. Flight Sim pages All the relevant text from the above link is below. IL:2 Sturmovik AEP The 2.01 patch to the Ace Expansion Pack adds a UDP server that will export a variety of instrument readings. UDP is a network protocol that can be accessed through use of Winsock, a Windows networking API. The 2.01 patch includes the file "devicelink.txt" that documents this feature. (Thanks to Jari-Matti for alerting me to this.) Mike Couvillion has an extensive C++ wrapper for device link. Check the forum on the Wing Walkers site for the code, sample applications and helpful comments. You might take a look at SimHQ.com in the IL:2 Sturmovik FB forum. There was a thread in early August, 2004 about "UDPSpeed", a program that makes use of the UDP server. It may serve as an example. It's a rather large and complex game. Although I'd love to hear of one, it may well be the case that there has been no concerted effort has ever been made in this regard. I couldn't tell from my quick look, but if the game uses the same game engine as found in another game by Ubisoft, you may cheat your way around it by finding a model extractor for the other game, before applying or attempting to apply it to IL2. Man, it really was easy when IDSoftware released the technical and programming info behind Quake, not to mention the 100kb document put together that documented 95% of the data file formats and game engine considerations of DooM.. I used Doom editors to mod DoomII, Heretic, Hexen and a few others that utilized the doom engine back in the day. Good Luck! Simon.
