While walking through the model it would be really cool if there were atmospheric effects:
- Obscuring rain (automatically 'fog' out the background and streaks in the zone. Options for density and direction.)
- Obscuring snow (like rain, but more gentle.)
- It would be cool if the effect could "light" the geometry in a similar way to sunlight but negatively (to darken where it hits) and add a reflective sheen to that surface.
Cloud cover increases to +200% so you can't see any sky.
The effect would be blocked by horizontal geometry (depending on the direction of the weather)
Any geometry assigned the "Vegetation" tag (including the grass) has a 'bend' and graphically streaks/moves/ripples with the direction of the weather effect.
It might be handy to assign "Zones" to have different atmospheric effects rather than a global effect... but maybe not.
Option to add rain on the camera lens (not enough to be distracting and towards the edges, but occasional streaks and drops that distort the image as they roll down the lens). Actually it would be cool to create a new texture tag that could be applied to any surface that would have this effect (eg on windows).
Assign a generic external sound and a new "negative" type of sound you can place to cancel out this audio.
