[Request] Dynamic Weather System

[SysVR]

Implement objects such as rain and snow as particles
Along with that, adjust the rain cloud and adhesion coefficient.

Under objects such as overhead lines where objects are set for automatic collection:
It is technically possible, such as not raining automatically.

Dynamic changes dynamically.
Specifically, it looks like random.
