3D model format: Difference between revisions

Revision as of 21:57, 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 V1.71 in the game binary

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 repurposed

All blocks seems to be 32-bit alignedIf 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?
2	0x28	0xbc	UV texture data?
3	0x2c	0xc0	vertex data?
4	0x30	0xc4	faces data?
5	0x34	0xc8	Textures names
6	0x38	0xcc	Offsets to texture names, absolute addresses in file
7	0x3c	0xd0	Each element is 16B long, ?, ?, float, float
8	0x40	0xd4	Holds IDs of elements in 7
9	0x44	0xd8	surface transforms data?
10	0x48	0xdc	surfaces data?
11	0x4c	0xe0
12		0xe4	for non-tracks it's size of 1 divided by 16, unknown for tracks
13	0x54	0xe8
14	0x58		for tracks offset marks end of file
15	0x5c	0xf0
16	0x60	0xf4
17	0x64	0xf8
18		0xfc	stores size of 20 divided by 0x90
19		0x100
20	0x70	0x104
21	0x74	0x108
22	0x78	0x10c
23	0x7c	0x110
24	0x80	0x114
25	0x84	0x118
26	0x88	0x11c
27	0x8c	0x120
28	0x90	0x124
29	0x94	0x128
