post what you have and i can make some pointers / help

Yes go in game and click model viewer you can look at the models all you want.

I am working on it now just need to figure out a few more things

There is no way to import them into max yet you need to wait. Here is the character list in regards to their arc files. 0000 - cpu dummy 0001 - Ryu 0002 - Chunli 0003 - Gouki 0004 - Chris 0005 - Wesker 0006 - VJoe 0007 - Dante 0008 - Trish 0010 - Spencer 0011 - Arthur 0012 - Amaterasu 0013 - Zero 00...

try changing some of the flaots your reading to half floats for uv's.
also dante's inferno is the same format

the whole model format is dead easy its almost the same as obj. just need the header sorted out to reach the offset table then you can import anything.

just place a header on the files they are so easy to convert...

re5 script works its the same engine endian big get idstring long get version short get files short comtype zlib_noerror for i = 0 < files getdstring name 0x40 get type long string name + . string name + type get zsize long get size long get offset long clog name offset zsize size next i the models ...

Just open up any file and go to offset 0x60 this is the file table size"right after RULEZPADDING " then there is 4bytes that are not needed might be an id. Then each entry is 0x14 bytes long this is a sample C0 04 00 00 #Offset 90 8D 00 00 #Size C3 2A 9D 02 #? 61 E8 69 72 #? 10 00 00 00 #...

its the same as resident evil 5 just wait for the ps3 version.

post a sample file.

No one can extract any xbox capcom game after devil may cry 4 they change things in microsofts compression so extractors will not work. No one has reversed the compression on the 360. the ps3 version will use zlib just wait for that.

got models

you did something wrong then it works i tried it on this file.
show the output from the command line

This is fairly easy format i am lazy but if you want to look at the files without names just run
c:\offzip\offzip.exe -a c:\file.bin c:\extract 0x0
you can easily see the textures and simple model format on the files it gives out.

Here is the new max script with weights
Thanks to fatduck for helping figure it out.
