port vehicles, weapons & stuff between battlefield games

hello,

i plan to convert some bf1942 stuff to vietnam and 2142 and also some battlefield 2& 2142 content to vietnam.

now there arent any tutorials about that. bfeditor.org is down which i asked there already few years ago for a tutorial to convert 1942 models to battlefield vietnam and i got one but now is gone since the forum is down.

my questions:

- anyone has a tutorial, how to port models and/or whole content (for example vehicle with code, tweak and all included) into another battlefield ? when i asked for the tutorial to convert between 1942 and vietnam, i remember some pieces of the tutorial, it was something like:

open bf1942 model > clicking a box which makes it bf vietnam compatible or something > export model to bfvietnam format or back to its origin format but now compatible for vietnam

but i cant remember exactly, oh and a plugin for 3ds max is needed to make it compatible with vietnam but i forgot what plugin

- in bf2/2142, you can port the stuff (including the code/tweaks for weapons) simple by copy & paste it, since its the same engine but a little modified and it works like a charm. does the same work between bf1942 and vietnam, or do i have to do the port with 3ds max ?

i need the plugin and a tutorial, it would also help other community members too.
if someone has a tutorial how to port models between 1942 and vietnam and/or from battlefield 2/2142 to vietnam/1942 and the other way around, please share it :)

thanks in advance
