1. Open the "New Scene" Scene in the attached "1261203.zip" project
2. Switch the build Platform to Android
3. In the Build Settings menu, enable Development build and Build and Run to an Android device
4. Inspect Frame Debugger for instanced shaders on the device

Expected result: there are fewer events and "Draw Mesh (instanced)" event is present
Actual result: there are more events and no instanced meshes drawn on the device

  1. Resolution Note (2020.2.X):

    Shaders that don't use SH per instance should use "#pragma instancing_options nolightprobe".
    Otherwise UNITY_SETUP_INSTANCE_ID should be use in the fragment shader.
