i was able to extract the stm formats (exient streamed envirnoment) of the tracks with this scriptstm.zip, though the model is in a .dat file format, the rest of the models in the game uses .xgm, exient's properitary model format

some of the files i was able to analyze inside:

.mp1 - material file

.tex - texture reference, game uses exient xgt

.q02, .q03 - submesh references

.pvs - scene file

samples:stm extracted.zip extracted .stm

https://mega.nz/file/4E8zHDJC#QczQ6FCOMqwbLZztg0rYsizyMPu7KCbPEHtTqrAHLUE original stm file (seedway track 1)

https://mega.nz/file/EcNXHZgQ#L1iaxk8zRciJ0--D_le57zmMFVtSZmDdUUNtTeDGFNM blast off model

https://mega.nz/file/ZEUwibYS#Y9SpTHJx1fMyTh44BCjiA6W2Hdy7OFQA9KSBpxNzEvA sub zero track 3

topic name is now changed because i found out other games than angry birds go use stm files

Got a track point cloud from the .dat file:

i have sent more samples, main post also updated

https://mega.nz/file/5VcjGZwC#5v4Fsw71b96aaOMdOnXY0nkcvUnOMT5Pqy6LTVNh_ow rocky road track 2

https://mega.nz/file/5Rd12RBQ#OoH37aYyyYPsfG3ofSsF3cPke3KBPK9l0uTxze78k_0 rocky road track 3

Tracks are boring, aren't they? How about a car model sample?

point cloud stunttrack3-dat

the cars are stored in .xgm instead, i think transformers uses the same format for it's levels

Yeah, they use xgm, and mariokart64n from XenHax already made a script that imports those into blender, levels and cars.
Tho, AB Go's format is different. I tried importing Go's track meshes with this, but it didn't work. Maybe someone could modify this script to work with those files?

XGM.py

Has anyone fixed the script for the track meshes?

stm, .dat, .xgm. Nobody clearly said what is what. Somebody said .stm are tracks, another one said .xgm are models (cars) but no one knows what exactly their format is.

No one wrote about the difference between Angry bird tracks and those of AB Go.

So I have my doubts that anyone will care for the XGM.py script.

this applies for the rest of the models besides the tracks (like the characters, objects, menu)

you do refer the game differentely, the angry bird tracks are the thing i'm talking about, there's no differences except the way it's said

Then you should change your thread's title which is "angry birds go track extraction"

"the way it's said"? What does that mean?

f1 2016 uses the same engine so i'm going to share the stm files as well, they're much bigger than the angry birds go ones

Obtuve una nube de puntos de seguimiento del archivo .dat:

Please explain to me how you got that point cloud from the .dat file, I need to know urgently.

Hard to recall one year later, no matter how urgent it is.

edit: I checked a .dat file and it's rather simple to get a point cloud. In a hex editor check for a block where the 4th dword in a 16 bytes row is FFFFFFFF (this may vary but the last byte usually is FF, afaics).

So with an FVFsize of 16, a suiting vertex count and the 'noPtC' button in hex2obj switched to PtCld you get a view of a track when pressing the 'mesh' button.

Es difícil recordarlo un año después, por muy urgente que sea.

Editar: Revisé un archivo .dat y es bastante sencillo obtener una nube de puntos. En un editor hexadecimal, busca un bloque donde el cuarto dword en una fila de 16 bytes sea FFFFFFFF (esto puede variar, pero el último byte suele ser FF, según tengo entendido).

Entonces, con un FVFsize de 16, un conteo de vértices adecuado y el botón 'noPtC' en hex2obj cambiado a PtCld, obtiene una vista de una pista al presionar el botón 'malla'.

Thank you so much, it will help me a lot to understand the track! My goal is to recover the Rocky Road secret path collision (because I removed the fence collision but the road has no collision), so I want to understand concepts first and go little by little, starting with the point cloud. Sorry for saying it was urgent. Honestly, I made a mistake when I said that. I don't know why I said it, but I really appreciate your help. Best regards.
