NpShape::setFlag(s): triangle mesh and heightfield triggers are not supported!

Getting a number of these in my U5 project.

This topic in the old Unity 5 Pre-Order forum (now closed) talks about it.
SuperPig also posted a small script:

Code (CSharp):

1.  
2. public void SelectAllMeshTriggersInScene()
3. {
4.     Selection.objects = FindObjectsOfType<MeshCollider>().Where(mc => mc.isTrigger && !mc.convex).Select(mc => mc.gameObject).ToArray();
5. }
6.  

But when I create the script in my project I get this error:

I'm not a scripting guy so could use some help with this.

Thanks

 

Getting same error: NpShape::setFlag(s): triangle mesh and heightfield triggers are not supported!
Is this something to do with .obj files?

"PhysX 3.3 doesn't support non-convex mesh triggers, so you're going to have to break your trigger down into convex pieces (or into overlapping BoxColliders or similar)."

Just got the meaning myself, but will have to wait until I can try it.

 

Create a new gameobject and add this script to it. Then put your gameobject to scene and run it.

You will see on Warning log, where it finds a "triggered" meshes.

using UnityEngine;
using System.Collections;

public class FindTriangles : MonoBehaviour {

MeshCollider[] glist;
void Start ()
{

glist = FindObjectsOfType<MeshCollider>();
foreach(MeshCollider mc in glist)
{

if (mc.isTrigger && !mc.convex)
{

Debug.LogWarning("Found 'triggered' mesh: "+mc.name);​

}​

}​

}​

}

 

Thanks, will check it out!
