The lack of vertex attributes causes a crash on dynamic batching

Mobile Rendering


Unity Player crashes when all the following conditions are fulfilled:

- Using OpenGL ES (2.0/3.0).
- Dynamic Batching is enabled.
- There is a vertex shader that needs a vertex color.
- A mesh without vertex color is given to that shader.

It’s reproducible on both iOS and Android devices. Note that it doesn’t reproduce when using Metal API.

    We have similar issue on Unity v4.6.8 for iOS IL2CPP build.
    Is it already fixed on Unity 4 version, instead of Unity 5?

    Can be the same thing ?

    If it is, it's still not resolved. Re-open the issue please.

    Unfortunately, this is not fixed in 5.0.1f1 still (for me at least).

    None of the temp fixes out there are working for me. Still occurring in 5.0.1 but issues have become more frequent with latest unity. Issue is related to the draw buffers.

    Same problem happens to us. Dynamic batching works fine on Android/Web and even iPad mini 3, but crashes on iPad 4. Turning it off solves the problem
    Tested with Unity 5.0.0p2 - 5.0.1

    Just happened to me again. This time using the built in Unity primitive Quad mesh and the "Mobile/Transparent/Vertex Color" shader -- crash!!
