New discoveries in the game's data files

[aybe]

Just found a new type of polygon: 0x14

These are found on COMMON\CAM?S.PRM files, the following length is of 52 bytes (vectors + something ?), still trying to figure out what these are 😅

Could these relate to the replay post each race ?

EDIT:

I am running a PRM validator against files in WIPEOUT\COMMON, for what it's worth, I am trying to make it pass the test, unless we know the real content I am simply skipping bytes to try achieve 100% success rate.

With the code from your experiment rate was 41%, now it is 76% 😄

I think that'll be a significant milestone once we reach 100% as at least we'll be able to read files from end to end ... until we understand them.

Here's the excerpt of the above test, suggesting it's replay-related as there are no vertices:

CLASS.PRM

Object 1 : LIGHTS

Vertices: 0
Polygons: 4

New polygons types:

• 0x16 : 28 bytes
• 0x15 : 16 bytes

Some light definition ⁉️

Object 2 : extru1

Vertices: 112 (offset 364)

Then there is a strange group just below which looked like vertices (64) but i don;t know, looks like a 5 branch star though:

Here are the 2 combined, star is on middle as cluster of dots:

The only hint in the header is Index1 if you subtract 100, though ...

Polygons: 118 (see just below)
I have a high confidence in it since manual count yielded same count as in header but there is a block of 448 * 8 bytes I couldn't explain the meaning, after the vertices and before those polys. To find this count I started counting right before next object and climbed up until reaching 118 polys.

2 new types of polys:

• 0x10: 28 bytes
• 0x12: 36 bytes

(total size incl. header)

You can make graphs very quickly using https://plot.ly/plot.

TBC 😄

EDIT I know I've already seen this model in the game but can't remember what is it ?

SKY.PRM

This file does not comply with the format, the name of each object is 256 bytes instead of 16.

There are many strings in it.

For the first time the 4th component of vertices are used but IDK why ...

sphere4_2

XYZ

XYZW

Not sure it is ever used, there is such object in every track, please confirm

EDIT: NO1.PRM has the same 256 bytes name
