Effect disabling entirely when no shadows present near camera about volumetriclights HOT 2 CLOSED

Yes, this is a known Unity issue (reported ages ago). Unity stops rendering shadows if there are no visible shadow casters. That's a good thing. But it also stops executing command buffers at that moment. This breaks the effect. There is no way how to detect it happened and so we can't do anything about it.

There is a simple workaround though. Place your camera inside a small shadow-casting 3d cube. The cube won't be visible from your camera because the back faces will be discarded by the rasterizer. This way there is a shadow-casting object in front of your camera at all times and Unity will be forced to keep updating shadows and executing our command buffers.
You could probably find a more elegant solution but the goal is always the same - force Unity to update shadows at all times. Hope this helps.
