Graph scan crashes the app on Android

General
#21

Also having this problem.

Here’s one thread in Unity on it:

https://forum.unity3d.com/threads/physx-crash-on-android-only-physics_custom_internal_call_checkcapsule.331106/

They basically refuse to fix it without a repro case, “play my huge game until my 3rd party pathfinder randomly causes this crash” isn’t really a repro case, so I doubt Unity will ever fix it.

Seems like the pathfinder need to work around this issue? Switch the capsule test to multiple sphere tests? idk…

Hello,

I just wanted to report that we’re also fighting with this issue. Unity 5.5.3f1 and AStar 3.8.1. This is the crash log:

We had a previous case of this problem and then it was caused by two capsulecolliders on the same position, maybe that helps to find a solution?

Thx,
