Hi! Yes, sometimes I still working on it, but I can't say that it will ever finished. The current state is:
Game world
All levels are converted to VE3 (world.map also), so you can explore the whole BP world, but only a few has working impostors, and mostly its ugly, because the impostor generator function is broken, and often crashes in LevEdit. And also they are using the old lighting, because the lighting smoothing function also broken and without that it has bad results on level edges if I recalculate lighting.
character models
All character models fixed, so they can use ragdoll when die, and also works with the engine bone control - so NPC's turning to you, and looking at you.
some old vehicles
A few BP vehicles converted to work with VE3's vehicle physics. Cars are not problem, but I still have to figure out how to make planes with wheels, so the wheeled cessna could be used too
game text and game objects
all game text (object names, mission texts, dialogues, etc..) and scenario objects are converted to a new resource.qrc
There are a lot of smaller works left, like recreating the scripts and events for missions (BP has them hard coded, but VE3 uses a new script system), fix the dynamic objects on levels by hand (VE3 doesn't uses some old classes, so this objects ignored on level converting), doors needs to be fixed, etc…
The problem is because of the broken important things (mostly the impostors) I don't really have the motivation. By the way there is always a way, I already solved this kind of things, for example the new .rf2 format, and the physics data in it - I've wrote a 3d editor for, or the .map format, also wrote a new MapPlanner, because the leaked version was broken, and unable to open files.
But from other hand - damn its 10 years since this game has been released... Is there anybody who interested in a mod for this game?
