Assertion failed: Invalid AABB aabb (and AABB a)

1) Name of tool
Probuilder

2) A brief description of the issue
As soon as calling `myPbObject.ToMesh();`, I get both these errors every frame until I exit play mode and all my shapes disappear / become invisible.

3) Your system environment (Operating system, version of Unity, version of tool)
Windows 10, Unity 2018.1.0f2, Probuilder 3.0.8 (Package manager)

4) Full description of issue
See short description.

5) List of steps, clearly explaining how to replicate the issue
Have a `pb_Object` and attempt to call `ToMesh()` on it.
On another project, I used to have the issue only raising if I did call it too early (specifically on Start) but later was fine. Here, even with a `yield return new WaitForSeconds(3);` it still happens.


6) Any other comments/etc
When building and checking out the output_log, there are more infos, which might be a lead. I still posted because the Editor didn't give any info nor googling the issue.

Code (CSharp):

1. // Not allowed to access triangles/indices on mesh 'Combined Mesh (root: scene)' (isReadable is false; Read/Write must be enabled in import settings)
2. // (Filename: C:\buildslave\unity\build\Runtime/Export/Debug.bindings.h Line: 43)
3. // Not allowed to access uv on mesh 'pb_Mesh736' (isReadable is false; Read/Write must be enabled in import settings)

 

That was it thanks!

A more explicit message would be nice to have!
