[Shaders] Shader _Time value isn't updated when there isn't a Camera in the Scene

Shaders

Shader _Time value isn't updated when there isn't a Camera in the Scene.

When you don't have a camera in the scene, just a Canvas set to Overlay, the shader animation (via shader code with _Time property) doesn't work. If you switch off Main Camera game object in testScene and close Scene View, leaving just Game View, and then hit Play, effect in Canvas will not be updated.

To repro:
1) Open attached project
2) Open testScene
3) Deactivate main camera game object and close Scene View tab
4) Enter playmode and see the shader animation (uses _Time) not playing on UI graphic
5) Activate camera game object and see animation working.

Reproduced in 5.3.8f1, 5.6.2p4, 2017.2.0b1.

  1. Resolution Note (2019.3.X):

    There is no nice way to force update the _Time or shader properties when there is no camera without rewriting a lot of systems which is not doable currently.

    Also happens in 2018.3.4f1.
    Annoying when you only want to display UI using Screen Space - Overlay.
