[PS2] Gantz NKP models and texture files

[shadowmoy]

hi there , just found out this mangas and the ps2 game derived from it, here is the nkp model files for kishiro if someone want to help on this one

the nkp files are packages containing several files, in it you can found:
- nkt witch is texture block that is also like tim2 files (paletized 256 color textures at what i have seen)
- nkm witch seems to be the mesh blocks
- some text files containing pointers ???
- nka for animations

i have not started to work really on this one yet as i am busy with lot of other projects so if someone want to start working on it , sample files are here:

I am sorry I cannot be of much help.

ok so i finally managed to convert texture to tga, each nkt texture have this structure:

Code: Select all

type nktheader
%magic         '//always &h1A54B4E ==441731918 ==( NKT &H1A 
$unkna * 36  '// 9 unknown integers
%paloffset     '//palette offset
%palsize       '//size of palette data in bytes (must be divided by 4 to get BGRA count)
$unkb * 224  '// another block of integers unknown
%width         '//texture width
%height        '//texture height 
$unkc * 168  '// another block of integers unknown
end type 

then you read the palette array
then you read the image indice data witch is always datasize= width * height
once done rebuild the image using the palette entries and do some stuffs to fix the palette order if needed
quite simple in fact.

now i will try my hands on the mesh format that looks real pain in ass
