Angry Birds Go! Secret Path Collision Tracks .stm

[Cookingcakes]

I need your help analyzing the track.stm file for Angry Birds Go! The file is located in apk/assets/data/environments/theme003 [models.pak and textures.pak are located here]/tracks/run006/track.stm (vfxlist.xml and track.xml are also located here).

I have a QuickBms script (TrackSTM.bms) that unzips this track.stm file and contains several files, such as:

1. track1.pvs (Potential Visual Set).

2. .mp1, .tex (their references are not found in track1.pvs).

3. terrain0x.q0x (.q02 or .q03).

4. road0x.q0x (.q02 or .q03).

4. kd1_0_0.dat.

 5. KDMetaData1.dat

The script:

What did I do to remove the secret path blocker?

First, I removed its visibility in the .pvs file. In a hex editor, I removed the reference to the terrain03.q02 file, filling it with zeros. (By the way, if I remove the reference to a road0x.q0x file in the .pvs file, when opening the track in the game, it crashes.)

To remove the collision barrier, I performed several trials and errors, deleting random bytes in the kd1_0_0.dat file, and I obtained these bytes responsible for the blocker.

 90 31 10 00 80 31 10 00 50 31 10 00 11 C0 0F BF 53 BD BD 3B 1B D3 53 3F 02 00 09 00 B9 26 06 44 9B BA 2D BF 24 4F E5 3B 5E 92 B7 C3 3B 5F 51 43 51 43 B8 BC 5C E7 B5 3D BA CD 05 BC 17 C8 4E 3C

So I cleared the blocker and successfully entered the secret path, but...

That wooden path in the secret path has no collision. So you fall into the void when you step on it, or rather, when you don't step on it, you just walk through it.

 I don't think those missing hex bytes will also remove the road collision because an acquaintance entered without direct modifications to the STM (flying with an air car), and effectively, there is no collision.

My goal is to recover the collision for that specific road.

By removing other random bytes, I was able to remove another portion of the ROAD from the track.

But I'd be interested in analyzing it with a tool like Model Researcher, MeshFinder, etc. (I only know those, but I don't even know how to use them).

That's why I'm asking for your help. Please give me the names of tools you think would help me analyze this track, as well as recommendations, opinions, and advice.

If you want to analyze it yourself, ask me for the files and I'll share them with you.

If you want to collaborate with me on this secret path, that's fine too.

I would greatly appreciate your help. Best regards.
