Terrain Bug on Unity 5.4.2f1 and Android 6+ devices...

I tested with both an Samsung S7 and a Motorola G4 Plus.

Create an empty scene, add a terrain, build and run and it works.

Create some texture and paint the terrain, the game will no longer work.

Error as follows :





Update: This only seems to happen when we build with Texture compression overriding for ASTC or ATC, I can't test other devices.

Edit: Also notice this is only on terrain, any other 3D object works.

 

After further testing, if I create a prefab with the terrain and delete it from the scene (disabling isn't enough, the game still crashes), and instantiate the terrain later via GameObject.Instantiate<GameObject>(Resources.Load<GameObject>("Terrain")); the game will NOT crash.

 

Please file a bug report Unity

 

Posting this here because this thread is the number one search result in Google for this issue...

This is a warning to anybody making a 3D game for Android... using a Terrain object will cause some Android devices such as Galaxy Note 3 to crash, while other devices like Galaxy S3 work fine.

If you create a new scene without a Terrain object, then the game works fine.
Btw simply removing the Terrain object from your scene isn't enough. For some reason you need to rebuild your scene without a Terrain object. The easiest way to do this without having to start from scratch is...

1. Remove the Terrain object from your scene
2. Create a new GameObject and drag everything from your scene into that GameObject
3. Drag that GameObject over to your Assets folder to create a prefab
4. Create a new blank scene
5. Drag your GameObject prefab into that scene
6. Everything should work fine now

You might then say, well I need something like a Terrain object for my game. The workaround is to create a huge Plane object as the ground floor of your game, then add some mountain assets to it, like these nice mountains...

Anyway this Terrain bug in Unity looks like it will be fixed in an upcoming release...
