Now you should add the offset backup to the current pointer you using
to get the content of.

Something like:
[LBA 1 & 2 for body] -> current pointer = backup content + backup offset;
[LBA 1 for anim] -> current pointer = backup content + backup offset;
- Note for LBA2 anim you should count plus 1:

[LBA 2 for anim] -> current pointer = (backup content + 1) + (backup offset + 1);

This is the LBA 2 equivalent to the LBA 1 File3d.hqr file. It contains entities of the game Actors.

Specification

 This page may need some cleanup. It should be reformatted to use wikitext instead of <pre> tags.

[#] [ INFORMATION ] ------------------------------------------------------------

This document describes the format in which the LBA2\Twinsen Odyssey File3D 
character informations) are stored in.


[#] [ NOTE ] -------------------------------------------------------------------


In LBA2 this only exists in one unique file which as all this information inside.
This file can be found inside Ress.HQR in the entry 44 (LBA2 Character Informations).


[#] [ FORMAT ] -----------------------------------------------------------------

s32 = signed int (32bit)
u16 = unsigned short (16bit)
s16 = signed short (16bit)
byte (8bit)
+ = to add previeous bytes count

The file is laid out like an HQR file, but does not have the size/compression header
at each offset given. Refer to the HQR document on how to read the intro.

00:	s32	First offset


Do this "number of entries" times
[ Entries ]

First of all you need to read the entry  content for each entry of course.
I'll assume you know this. Also you need to create a variable or structures
to handle the anim and body content and count.

Do the next block while the read byte is not 0xFF (End of each entry content).

[ Content ]
+00:	byte	Opcode

Opcode = 1 -> Body content
Opcode = 3 -> Anim content


[ Body = 1 ]
+00:	byte	Body index
01:	byte	Body data size - 1 (only take the following values)
		|-> 0x04 (4) -> When no collision box is used
		|--> 0x11 (17) -> When used a collision box
02:	s16	Body real index (in BODY.HQR)
04:	byte	Collision box flag
		|-> flag = 0x00 (0) -> Model doesn't use collision box
		|--> flag = 0x01 (1) -> Model use collision box

[ IF Collision box flag is set ]
05:	byte	Number of bytes to read minus 2. 
		In this case the value is always 0x0E, so it will have more 0x0E-0x02 = 0x0C bytes
06:	u16	X (bottom left)
