Getting an error in CombineChildren.cs what to do?

Go the following error after running combine script.
Maybe joe can help me with this?
Thanks

Failed getting triangle strip, triangle indices are not stripified. use Optimize to stripify them.
UnityEngine.Mesh:GetTriangleStrip(Int32) (at /Users/joe/iphone-clean/Runtime/Export/Generated/Graphics.cs:1069)
MeshCombineUtility:Combine(MeshInstance[ ], Boolean) (at Assets/_Scripts/MeshCombineUtility.cs:27)
CombineChildren:Start() (at Assets/_Scripts/CombineChildren.cs:83)

[/Users/joe/iphone-clean/Projects/…/Runtime/Filters/Mesh/LodMesh.cpp line 573]

I’m getting a similar error, with different root cause:

NullReferenceException
UnityEngine.GUILayer.HitTest (Vector3 screenPosition) (at /Users/joe/iphone-clean/Runtime/Export/Generated/Graphics.cs:2609)
GUIButtonSwitcher.Update () (at Assets/_Scripts/GUIButtonSwitcher.js:94)

Anyone know what causes this? Or who Joe is? :slight_smile:

Thanks,

Galen
