curvy at small scale?

yes it seems this doesn't let Unity build to iOS, I get the following error

The issue I spoke about, and described in the link provided in my previous post, is not a build error. I will be very surprised if the error you had has anything to do with changing the value of Max Cache PPU. But I might be wrong.
To properly investigate the issue you encountred, can you please answer these questions:

• Do you confirm that this error does not occur when Max Cache PPU has a value of 8?
  
• If so, what value of Max Cache PPU triggers the error?
  
• Do you get the same error when building a Standalone build?
  
• If not, what are your iOS build settings and player settings?
  
• Can you send me a scene or a project where the issue happens?
