Failed opening GI file

Unity Engine
1

After starting Unity 5.1.1p2 on Windows 8 today I suddenly get 3 warnings and 3 error messages in the console:

  • 3 times “Mesh doesn’t have normals. Please create some for Enlighten.”
  • 3 times “Failed opening GI file: ‘1a/1a592adcc158728e77b03d3440e421bf.ppg’.” (with different files)

It used to work for weeks with no issues. There are no additional infos as to which mesh is concerned. Double clicking the warning shows an empty inspector and some weird faces in the bottom that don’t comprise any of my objects. There is no way to get rid of these messages as soon as precomputed GI is activated.

When baking I get even more errors:

  • "m_InstancePositionsInSystem >= 0 || (GetHighestLODLevel (inputData.m_LodMask) > 0)"
  • “Failed reading item 0x00000000000000000000000000000000 .”
  • “Failed loading input geometry for object with hash e5cddad334a09155c28e1df7c588248d.”

I deleted the GI cache through the preferences and manually. I cleared lightmaps and baked, I removed baked GI and have only precomputed. Nothing helped. Any ideas how to fix this?

Positive thing, in 5.2b1 only the 3 warnings remain, the errors are gone. Really strange. Still not helping too much though finding the root cause.
