Van Helsing PS2 .bin models

I am here to ask if someone please can help me exporting the contents of .bin files from Van Helsing PS2 game, it contains 3D models and its textures from characters and missions.

Didn't bother searching for face indices:

(Small submeshes of about 137 vertices each need to be assembled.)

collected some submeshes (vertex count 42 may be too low for some of them since I didn't search for the correct value)

(In the lower part I chose vcount=79, maybe grabbed some normals thus.)

So it looks like the sequence is UV, Vertices and then the normals.
You may need to create a .bms script to extract the files,
perhaps the file structure appears to be:
Code: Select all
long - number of files
long - starting address
long - unknown
long - unknown
long - name address
long - unknown
long - file size
long - unknown
long - unknown
long - unknown
long - FFFFFFFF?

bms scripts are used for decompressing, usually. But I didn't see compressed parts in the grp.bin file. Did I miss something?

Files are concatenated, if you go to offset 0x5DD8 you will see a list of filenames contained in ND_R01.GRP.bin
I believe that for a better handling of these files it would be easier if they were not in a single file.

Code: Select all
int num_file
int data_offset
int unk //32
for (num_file)
int unk0 //always 0
int offset_name
seek (offset_name) >> string name
int unk1
int size_data
int unk2 //always 0
int unk3
int unk4
int unk5//always -1
int unk6//always 0
seek (data_offset)

I see the point. Thing is that the character file VANHELSING.GRP.bin contains about 109 small submeshes with 40..80 vertices. Not sure whether dividing up to separate files gives an advantage (maybe some of them are bigger, just used 42 and 79 as quickhack vertex counts for them all, no time to care for it atm).
Maybe level files contain bigger parts. But usually you'd treat levels "undivided".
btw, there's "Created by: JOF2MDL Ver 1.6" in the .bin file. Anyone knows this tool?
well, this one is dead ugly (some details look correct):

Hi, I was doing some research(yes, a year later, lol) but I used XBOX files. I think is more easy to understand, I analyzed an enemy "OWL" (OWL_BASE.GRP.bin) so I cut the mesh part(mdl) and pasted this in a new file("OWL_BASE_model"), this was what I found:
With that info I used model researcher, now we have the complete mesh:
But it looks like a mess.. I guess we need to apply the skeleton but I don't know how to do that. Skeleton in "OWL_BASE.GRP" is at 0x49A80.
Some notes:
-OWL_BASE has one mesh, other characters/enemies have more meshes. For example Van Helsing has more meshes for the head(Face, hat, hair. etc), the rest of the body is in one single mesh. You can find a mesh for the shadow too.
-VANHELSING.GRP.bin has meshes for weapons and effects, the model is in "VANHELSING_BASE.GRP.bin" so models for characters/enemies are in "xxx_BASE.GPR.bin" files.
-Textures are DDS so it is easy to extract those.
-There is a table about material(?) before each mesh(mdl).
Here are some samples:

OK, that is all. I hope this helps a little bit, Thanks for reading all this crap
