Football Kingdom - Trial Edition, models files nudp .nud

[im_a_moth]

Hi guys im looking for some help to understand the files from the game mentioned on the title, the file that im attaching is a ball model the only thing i was able to tell was this

4 bytes magic(NUDP);
uint size;

//unknown data until offset 0x114

uint id1?; //some id that indicates if its vertex data? in some models is 0x01000103 or0 x01000105
uint unknown;
uint vertexCount;

16 unknown bytes

vertex data, 32 bytes per vertex (still unsure but most of those values looks like floats)
uint or float unknown2;
uint id2?; // depends on the model, in this case 0x010003030
uint fixed1; //always 0x20
uint fixed2; // always 0xffffff7f

triangle data?

 

any help would be appreciated!
