Um..what format? I use milkshape, so I should be able to. It supports alot of stuff. Just e-mail them to me and I'll see if I can do it. If not with milkshape, I have deep exploration (I found it doesn't *seem* to export animation FROM .x, but maybe to .x).
EDIT: Oh, lightmapping will be in it once I finish the other level. It probally won't have a BFG, as I doubt I'll even find a plasma gun. As it was I wasn't going to have real imps, just zombies with gernades. It will, however, include these weapons:
*Pistol (In Demo)
*Shotgun (Mossberg)
*Supershotgun (That scifi shotgun)
*Chaingun (Well, the chaingun)
*RocketLauncher(LAW)
The supershotgun is a maybe, but it would only contain like 1-2 shots like the one in doom. It would be very powerful though.
