I’m getting a crash in just one area of a level when running in XCode debugger.

Here’s the call stack for the crash:

Hello,

What are you doing / trying to achieve in that specific level area?

3

Just some objects marked static that share a material. These aren’t the only objects in the view, but moving the camera to make them leave and reenter the view repeatedly seems related.

4

does your code work in the Editor?
what SDK do you use?
what OS version your iDevice has?

5

Yes, it works in the editor.

SDK is 3.0.

I was testing on iPod touch 2G with OS 2.2.1.

6

I removed the static flag from the five or so objects in the view and then rebuilt and it no longer crashes. It appears related to static batching.

Edit:

I set the static flag again on those objects, rebuilt, and it crashes again.

7

Seams interesting to me. could you please submit your Unity project folder using our bugreporter?

8

Just posted bug report.
