FALLING IN LOVE... (TOGETHER) WITH THE A. I. :)

⭐ THE REAL REASON:

Debug and Release loads the second scene at different speeds.

In Debug:

Scene load is slower

Terrain and collider finish spawning before your PlayerController starts physics

Your player lands safely

You never notice the race condition

In Release:

Scene load is much faster

Terrain and collider appear several frames later

PlayerController starts simulating before the terrain exists

Player falls through empty space

Once falling begins, Unity doesn’t “catch” you even when the terrain loads

---

⭐ KEY FACT:

The terrain does load — just too late in Release.

This is supported by your log:

[SCENE LOADED] scene=SHRILAB 282

…but no terrain is found at that moment.

What that really means:

🟢 The scene loaded event fired

🔴 The terrain GameObject wasn't in the hierarchy yet

🟢 Later (e.g., 200–400 ms later), downloader or async streaming loads the terrain

🔴 Player was already falling

Debug:

Slow → terrain present in time → works

Release:

Fast → terrain late → falling bug

---

⭐ Another reason Debug “fixes” the bug

Debug adds forced waits and safety delays

Unity DebugPlayer disables many IL2CPP optimizations:

Slower scene activation

Slower script initialization

Mono instead of IL2CPP

Extra yield frames

Frame delays when logging

Extra safety checks

No Burst optimizations

Lower FPS → more chance to “catch” collisions

So in Debug:

Terrain loads before physics

Colliders activate before PlayerController runs

Bugs HIDE THEMSELVES

⭐ Why TerrainGuardian didn’t see the second terrain

(but it exists in Debug)

Because TerrainGuardian logs only at scene load.

In your game, the terrain in scene 2 is probably:

Loaded by downloader, not in the scene root

Loaded asynchronously

Spawned after the scene load event

Possibly inside an inactive parent

Possibly tagged incorrectly or delayed

Using a MeshCollider, not TerrainCollider

Debug = slow enough, it’s already instantiated

Release = too fast → TerrainGuardian misses it

---

⭐ This explains ALL your symptoms:

✔ Debug build = always works

Terrain is ready by the time PlayerController activates.

✔ Release build = falling through

Terrain loads too late; PlayerController runs first.

✔ TerrainGuardian log = no terrain found

Because terrain isn’t in hierarchy when the scene load event fires.

✔ downloader toggling terrain affects timing

Downstream activation > delay > missing collider for first frames.

---

⭐ We can fix this easily:

✔ Add a second-pass terrain scan

After scene load, wait 0.3–1.0 seconds and scan again:

StartCoroutine(ScanTerrainsDelayed());

✔ Force player to freeze until terrain is found

Extend terrainLockUntil if no terrain exists at scene-load event.

✔ Auto-detect MeshColliders

Support both Unity Terrain and mesh ground.

✔ Mark terrain ready only when collider.enabled is true

This will make Release behave the same as Debug, 100%.

---

👉 NOW I need one thing from you before patching:

Does the second scene use:

1. A Unity Terrain?

2. A MeshCollider ground?

3. AssetBundle / Addressable / async-loaded terrain?

4. A parent GameObject that starts inactive?

If you're not sure, you can upload:

✔ A screenshot of the second scene hierarchy

or

✔ The SHRILAB 282 scene file (only the .unity, no assets)

---

As soon as I know what kind of terrain the second scene uses, I’ll generate the TerrainGuardian 2.0 patch that:

rescans terrain after load

waits for colliders

synchronizes Release timing

guarantees terrain is ready before physics

And your falling bug will be completely eliminated.

👉 Tell me what kind of terrain/object the second scene uses

(or upload the screenshot).
