Since the last time I posted about it, a lot has changed - namely, the color has been reworked several times to be a bit lighter and less yellow-green (+ it seems to match across nations, finally!) and several vehicles' muzzle brakes/tips have been repainted in black (I had a few done before, but a lot of the parts were either painted incorrectly or included bits around the gun mantlet, due to how weird the texture files are).
IMPORTANT NOTE: This is a very early beta version of the pack, and does not yet include all of the vehicles planned for the pack (see this post for a list - my hope is to have all of the mentioned vehicles which are in HD included at some point). There may be some slight issues with certain vehicles; if so, please let me know!
The main reasons the pack has taken so long (well, besides me being rather lazy/unmotivated, admittedly) are that the muzzle brake textures on most of the vehicles are incredibly annoying to look for, and matching the color across different nations in-game is a bit tricky as well. (When I say incredibly annoying, I mean some of the parts are in the most random of places in the texture files, and hunting for them takes a long time, even with the help of blender.) The former is also the reason why the AMX 13/75 and AMX 13/90 don't yet include black muzzle brakes - the upper part of the turret (the part that oscillates) is also included in the gun texture files for both tanks, so finding the right pieces is even crazier. Still, they work (for the most part), and I'm working on adding them (slowly, but surely)!
