StackOverflowException in ScanAsync

General Recast graph
1

Hello,

I am getting StackOverflowException while performing “AstarPath.active.ScanAsync” on two Recast Graphs. It happens only after game is built. No issue when the scan is performed in the editor.

I am not sure what I am doing wrong.

Unity Debug Exception: "StackOverflowException: The requested operation caused a stack overflow."

Hi

Which version of the package are you using?

Hello,

Version 5.1.6

Ok.
I haven’t been able to replicate this.
Can you replicate it in any of the example scenes?
If not, would it be possible for you to share a test project with me that shows the issue?

I will try to prepare some example project. I think I have a lot of RecastMeshObjects in scene. I am using them as static “cuts” to the RecastGraph. I have around 8000 in the scene. It is quite big scene, but I am scanning only chunk of it.

I was investigating it a little bit more.I found out that the issue was caused probably because we accidentally put RecastMeshObj on the terain and forgot to remove it.

But I was not able to replicate it in the sample project even with this knowledge.
Anyway. This is solved. Issue was on my side, sorry.
