I am trying to import a plumbing model into Unity as an FBX file and would like it to have collision detection. Now before i generate any colliders from the model the game runs flawlessly on iOS, but after generating a mesh collider from the FBX file the game crashes on iOS regardless if the mesh collider option is checked or not in the prefab. Can anyone explain to me what is happening and if there is a fix/optimization that I can implement to get around this issue. Anything would be helpful. Thanks.

The poly count is extremely high, but the mesh renderers aren't causing any problems for the iPad. It's only when I had mesh colliders to the scene. I seem to be hitting a limit to the amount of mesh colliders allowed in one scene. It actually says:
Is there a way to generate mesh collider's on the fly or load mesh colliders in batches? I think that is what is causing iOS to crash

first, i would check your poly count on the FBX mesh...it could be huge and rendering every frame might crash it.
additionally, is FBX the only way you can import it? i've had trouble with FBX in the past and generally import 3ds files.
Can you share with us the log from the game as it crashes. The crash might be totally unrelated to the FBX.
