Weird errors and the mesh disappears

I built with ProBuilder and suddenly these errors appear:

Failed setting triangles. Some indices are referencing out of bounds vertices. IndexCount: 7155, VertexCount: 4493 UnityEngine.Mesh:SetIndices(Int32[], MeshTopology, Int32, Boolean) pb_Object:ToMesh(MeshTopology) pb_Object:ToMesh() pb_Object:Awake() IndexOutOfRangeException: Array index is out of range.

What can I do to work on it again? Or are hours of work away?

Hi there- we'll need more info before we can help, can you let us know the basics first:

1) OS
2) Version of Unity
3) Version of ProBuilder
4) Build Target
5) If you create a new, blank project with only ProBuilder installed, using the same versions and build target, does this error still occur when clicking "Build"?

Thanks!

 

1.) Windows 7
2.) 2017.3.1
3.) 2.9.8f3
4.) Target Platform: Windows
5.) The error happend, when I built with ProBuilder in the editor. Suddenly the Object disappeard. So I don't know, when the error occurs or why or if it is repeatable. I just want my object back ^^.

If I can't get it back, I will create it again. Will take some hours, but who cares. ^^

 

Hi! Thanks for the info

I'm unable to repro this, sounds like you have a custom script affecting the object? For number 5 on the list, it's important to create a brand-new project, not just scene, and try it there.

Also, if you are able to upgrade to Unity 2018 and ProBuilder 3.x (Package Manager), that would be best, there have been many bugfixes and improvements. I'd give that a shot for sure

 

Can't upgrade to 2018 at the moment, because not all my assets are 2018 ready. ^^
and I don't have any custom scripts on the object. Only the normal ones: Transform, Pb_Entity (Script), Mesh_Renderer, Pb_Mesh 135296 (Mesh Filter), Mesh Collider, Pb_Object (Script).
Could the Triangles count be the problem? I have over 2000 tris on this object. Maybe ProBuilder can't handle this much?

I will try to build it again and lets see if it happens again.
