Introduction
Acknowledgements
This body of work is due to Synide's sweat and tears. To whom, all honour and glory. Ably assisted by T_D and Mikero that further detailed the data and gave this article a more general and correct structure.
General
The general format of an ArmA ODOLV4x p3d model is similar to the ODOLV7 format. The major differences are that ArmA models have
- an optional model.cfg, and
- Lods occur in the file from highest to lowest LodType value.
Legend
see Generic FileFormat Data Types
Relative Coordinates
All coordinates are relative to ModelInfo.CentreOfGravity
File Paths
The PrefixRoot\ folder.
Life for modellers would be far less tedious if filenames could also be relative to the p3d they are encountered in. Altering or moving or renaming the pbo (and specifically it is prefix) would not alter the relative location of the paa's it contains.
BI choose to use hard-wired Pbo-Prefix-addressing ONLY.
All hardwired addressing is relative to a built-in-situ (ie virtual) PrefixRoot\ folder
Each and every pbo in Arma contains a unique identity name, a prefix. Irrespective of the name of the pbo, the prefixname is THE name of the pbo from the perspective of the engine. In most cases, the prefixname is, conveniently, the filename. One huge advantage of this mechanism, sorely sorely missed in OFP. is that self-documenting increasing revisions of an addonV123.pbo can be supplied to Arma, with no changes to the mission sqms and other pbos that refer to it.
The PrefixRoot\ folder contains the prefix names of all pbos encountered (almost) ANYWHERE.
Thus the pbos in the Official Addons folder, the Oem Mods\Addons folder(s), the Dta core and bin pbo's, are all examined for their unique prefix names. These prefix names become the dictionary index of where the pbo really is, AND, what filename it actually is.
Thus all filename references in a p3d, *unconditionally* contain a prefixname\someFile\SomeWhere.
In most cases they refer to the very same pbo as the containing p3d and a great pity that the extraneous information could not have been removed by (optional) relative addressing as it requires a great deal of fiddling about when modifying models.
Note also that there is some inconsistency in filename paths. Most do not have a leading \. Some, require it. Both are indeed \hardwired
An Example:
P3dProxyName ="\ca\a10\agm65";
The immediate (and unfortunate) impression is that there is an A10 folder inside the official CA.pbo addon. In fact, the prefix of the A10.pbo = "ca\A10". Thus this reference is to the A10.pbo within which, is a agm65.p3d in it is root folder. (and again, this reference is in fact an extraneous reference to itself since the referring p3d (A10.p3d) is in the same pbo)
Versions
This Document covers ODOL versions:

VBS2
• ModelInfo now has a 24 byte thermal profile appended
V43 (Arma2a)
- As per VBS2 plus
- An extra byte at end of Skeleton structure: always 0
- LZSS compression is still used at this level

An optional prefix declaring the actual location of the p3d was introduced for arma3 (2nd version). Idiotically, it means the p3d cannot be moved out of it is current pbo.
The prefix is optional in the sense that it may be null. ("\0")

A face data struct only exists for those lods who's UseDefault is zero
ODOLv4xLod
- Lod layout corresponds to Arma1 (type40). The differences in a2 are in the nitty gritty of the structures themselves. Arrowhead(v50) has some changes.
- TrueArma2 == type 47 or greater (lzo compression)
- Type 43 was a preliminary p3d prior to lzo compression. rarely encountered

VertexTable
all arrays are subject to compression
struct { UvSet DefaultUVset; ulong nUVs; //in error, V47 sometimes sets nUV's as 0 but means 1 UvSet UVSets[nUVs-1]; ulong NoOfPoints; XYZTriplet LodPoints[NoOfPoints]; ulong nNormals; (A2)LodNormals LodNormals[nNormals]; ulong nMinMax; (A2)LodMinMax MinMax[nMinMax]; //optional ulong nProperties; VertProperty VertProperties[nProperties]; //optional related to skeleton ulong Count; VertexNeighborInfo neighborBoneRef[Count]; //optional
}
- All non zero counts counts are the same.
- Points,PointFlags, Normals and UV1 arrays are an integral group, they are either all there, or not specified (RacetK.p3d, a FrameTime lod has no counts at all)
- UV2,MinMax, VertProperties and Unknown are optional in the sense that their counts can individually be zero, else they are the same as the others
- In Odol7 PointFlags are part of this stucture, in Arma, they are a separated table.
CompressedFill Arrays
LodPointFlags, LodUV's and LodNormals arrays are not only subject to the standard 1024 rule compression, but also have a fill byte.
struct { ulong Count; tbool DefaultFill; if (DefaultFill) type Array; // default fill for all Counts else type Array[Count]; // potentially compressed }
The structure either contains a single set of type variables, or, an array of type variables. If a full array is declared (DefaultFill =false) then that array is subject to the 1024 rule as per normal.
UVset
if TrueARMA2 float UVScale[4]; endif (A2)LodUV LodUV;
LodUV
CompressedFill type = UVPair // eg float U,V;
A2LodUV
CompressedFill type = float // eg float UV;
LodNormals
CompressedFill type = XYZTriplet
A2LodNormals
CompressedFill type = CompressedXYZTriplet
CompressedXYZTriplet
contains 3 x 10 bit fields in a 32bit 'integer'
code for converting back to a standard XYZTriplet is:
void DecodeXYZ(ulong CompressedXYZ, XYZTriplet *triplet) { double scaleFactor = -1.0 /511; trp->X=trp->Y=trp->Z=0.0; int x= CompressedXYZ & 0x3FF; int y = (CompressedXYZ>> 10) & 0x3FF; int z = (CompressedXYZ>> 20) & 0x3FF; if (x > 511) x -= 1024; if (y > 511) y -= 1024; if (z > 511) z -= 1024; if (x) trp->X = (float)(x * scaleFactor); if (y) trp->Y = (float)(y * scaleFactor); if (x) trp->Z = (float)(z * scaleFactor); }
LodPointFlags
CompressedFill type = ulong bits
This table is the equivalent of Oxygen's points->properties dialog box. It specifically stores the user values and other flags for that point.
In ODOl7 it was part of the vertex table. In Arma, it is separate.
LodMinMax
CompressedArray { XYZTriplet MinMax[Count][2]; // 2 == min vs max }
A2LodMinMax
CompressedArray { float MinMax[Count][2]; // 2 == min vs max }
VertProperty
CompressedArray { ulong index;// seen range 0..4 ulong a,b; // definite not floats. might be flags, or indices }
VertexNeighborInfo
CompressedArray { ushort vertexIndex _posA; AnimationRTWeight _rtwA; ushort vertexIndex _posB; AnimationRTWeight _rtwB; }
LodBoneLink
LodBoneLink { ulong NoOfLinks; //range 0..3 ulong Value[NoOfLinks]; //the 'Value' seems to reference the 'LodItems' structure, resulting in a circular-reference. }
LodMaterial
Basically... A direct replication of the information in the given .rvmat file
The stages in the p3d include a default stage and a TI stage that are not normally listed in the rvmat.
- The first stage (in the p3d) is unconditionally the default stage. It is defaulted to empty (RvMatName=""), unless, specified in the rvmat
- The last stage is the TI stage, and is also defaulted empty, unless specified in the rvmat.
- TI Stages were introduced for operation arrowhead. Lod Material Types 9 and 10 (Arma1 and Arma2) do not have a TI stage at all.
Neither of these two special, hidden, stage types use uvsets. The transform matrix for them is defaulted empty (so-called 'TexGen0').
When specified in the rvmat (class Stage0 and StageTI respectively), no class uvTransform is declared for them. It is assumed default empty.
In an rvmat, uvTransforms are ordinarily declared within each stage body.
In a P3D, identical UVTransforms are declared once, and multiple 'stages' refer to them. There is, always, a default UVSet0 Transform as the 1st entry. (IE some stages dont require uvsets)
This P3D style can, if preferred, be used in rvmat syntax as
class TexGenX { ....... };
class StageZ { ......... Texgen=X; };
where X and Z are numbers

- Each lodmaterial entry contains a default StageTexture and StageTransform as the first entry. It is not shown in the rvmat file and has no PaaTexture
- It is the only entry if a SurfaceName exists.
A3_Physics Type1 (optional)
{ A3_stanza A3_stanzas[...]; // optional float aFloat; }
- The type1 structure may not be present at all, or, only contain the single ending float
A3 stanza
{ //header////// long Xcount,Ycount,Zcount; float floats[4]; long minCount; //Always2; long maxCount; //Always4; ////////////// float frames[Xcount*Ycount*Zcount][5]; }
A header with no frames is legal, it is XYZcounts (and floats[4]) are zero.
A 'stanza' consists of 5 float values. The amount of stanzas (if any) are determined by the 3 counts.
The range of each count value varies between 2,3 and 4.

- The first stageTexture is a dummy entry. For N humanly readable stage classes, there are 1+N LodStageTextures
- Later p3d formats (VBS2, Operation Arrowhead) append an additional classTI LodStageTexture. if not present or declared in the rvmat file, it is a dummy entry. The rvmat gui editor from BisTools is not able to display this.
- The TransformIndex is generally iterative (linear sequential). 1st entry is 0, 2nd 1, 3rd 2, etc. It refers to the nTH Transform Matrix
- TextureFilter maybe 1 of the following values.
- 0: Point // sometimes
- 1: Linear // rarely
- 2: TriLinear // not seen
- 3: Anisotropic (default)
LodStageTransform
LodStageTransform { ulong UVSource; float Transform[4][3];//a DirectX texture space transform matrix };
- UVSource corresponds to the 8 possible uvsets available
- 0 "None"
- 1 "Tex" default
- 2: "Tex2"
- ........
- 8:"Tex8"
- Tex1..8 cannot be taken literally as uvsource 1..8. They can mean anything, according to the template and are scarcely encountered

- See Named Properties
Decompression
see Compressed LZSS File Format
see Compressed LZO File Format
In ODOL v40 and v43 format files, some of the data structures present in the file are compressed by using LZSS compression.
ODOL v47 and v48 use LZO compression. This is represented as
Unlike pbo compression, in ArmA model files, one only knows the number of items to decompress, the expected output size (in bytes) and the expected checksum. With this information and the size of a given data item one has the necessary information to expand the data to it is original format and size.
Note:- Data structures that are identified as being compressible will only be compressed if the 'expectedSize' is >= 1024 bytes.
V64+ v64 implements a new flag for all compressed blobs. They no longer follow the 1024 byte rule. All possibly compressed arrays are now:
ulong elementCount byte compressed
0 - not compressed 2 - compressed
byte data[elementCount]
As an example if one was expanding the array of vertices positions...
- A vertex is described by it is x,y,z coordinates which are floats. A float is a 32bit (4 byte) number.
- If we were processing 1968 vertices then our expected output size would be 1968 * (3 * 4) = 23,616 bytes.
This 'expectedSize' is the only necessary information one would need to pass to a processing sub-routine or function.
Reference Tables
Material Stages
The number of material stages is dependant on the type of Shader that is used to process the material by the ArmA game engine. A reference table is used when processing materials where depending on the shader specified the given number of stages should be processed.
