Question of a noob editor

[Bouledeneige2]

i'm trying to customize rebellion a bit. No problems with importing cards for characters, troops etc...

But i'd Like to change the 3D model of the bulwark by a bigger Mon cal (home 1).

I downloaded resource hacker, and the model importer, but i can't get it done.

Any body can help me?

Which version of the Mon Cal are we talking about? The .rmd one?
