Still no success.
So here what i've done :
- exported all the objects of the animated model of the flag, found in Flag.dat (in Library folder), I get 26 files : one named FLG.obj, and the others are FLG_00.obj to FLG_24.obj.
- imported them in Wings3D, resized and exported them.
- opened the .dat file of a battleship, added a node with a 3D model, imported the animated flag by choosing FLG_00.obj
- added an animation controller
In S3D, the flag is animated when I click on "play". But not in the game !
So what's wrong, guys ?
