I am on Unity 2017.1 I get this error, no crashes or problems in editor while using 'private void OnBecameVisible()' . When I will switch to 2017.2, will tell if the error is still there.

Our game started crashing as soon as we updated from 5.5 to 5.6.
Reason is a "(wrapper managed-to-native) UnityEngine.SkinnedMeshRenderer:set_updateWhenOffscreen (bool)"
This def. needs to be addressed in 5.6

I got the same error when enabling/disabling child objects from a GameObject that had an animated Skinned mesh (aka an Avatar).
Fixed it by disabling the entire gameobject before applying said changes, and re-activating it at the end when finished.
Sigh.

Seeing this as well, this seems to be something specific in 5.6 as it only started occurring when updating from 5.5 (no code changes outside of the update).

I have the exact same error popping up, crashes on android device, the way it is reproduced in my project is I have a system that manages LODs of skinned meshes, the animator of these meshes are set to always animate. the error pops up when I switch from one skinnedMesh to another switching the LODs essentially, also from the log of my android device it crashes and displays these lines:

something to do with the skinnedmesh's offscreenupdates I guess? it is also reliably reproduced in an asset from the asset store name MeshBaker LOD in the SkinnedMeshSceneMob scene.
