Revision as of 21:03, 8 January 2021
Stores 3D models, more investigation needed.
Thanks to Martin for initial format reversing.
- Magic -
PMD V1.83- some files use version 1.82 instead, but they aren't used by the game, the engine in PC version won't recognise anything other than 1.83
- There is one unused mention of
PMD V1.71in the game binary
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x18? | Magic - PMD V1.83
|
| 0x18 | 0x4 | Type - 0 = shadow & skybox; 1 = track; 2 = car |
| 0x1C | 0x4 | Zeroes? |
| 0x20 | 0x94? | offsetsTable |
| 0xB4 | 0x94? | offsetsTable sizes |
offsetsTable
You have to add 0x148 to each value to get proper pointers
Bold IDs are in all files, rest of them are specific for tracks
Some of these are either unused or possibly repurpesed
All blocks seem to be 32-bit aligned
If the offset/size address is empty it's always set to zero
| ID | offset | size offset | Description |
|---|---|---|---|
| 0 | 0x20 | 0xb4 | Martin think it might be some sort of colider |
| 1 | 0x24 | 0xb8 | polygons data? |

| 10 | 0x48 | 0xdc | surfaces data? |
| 11 | 0x4c | 0xe0 | |
