snow/rain plugin in polygonal area (window)

Hi everyone. i just purchased krpano and i need to apply de Snow / Rain Plugin to a particular area of the pano,IS THAT POSSIBLE???, i can't find that option in the plugin.
maybe aplying de plugin to a hotspot?
hope anyone could help me. i really need to do this.
Thanks and sorry for my bad english.

maybe there's no need to use the plugin for this. Maybe just adding a gif of falling snow as a hotspot ?
Anyone?
Ideas?

Tanks Umalo! it worked great! you are god.

there's another question: if i have multiple windows (polygonal hotspots) and i want to make the snow to show on every hotspot, can i make a signle mask with all the hotspots at the same time??
becouse setting 5 different snow plugins (one for each hotspot) makes the pano really slow.
could i do something like this?

<plugin name="snow"
url="snow.swf"
flakes="40000"
color="0xFFFFFF"
...
...
rainwidth="0.5"
rainalpha="0.5"
mask="hotspot[hs1] + hotspot [hs2] + hotspot[hs3]"
/>

Or maybe making a "not conected" hotspot with diferent areas
I mean: hotspot 1= "hostpot A" union "hotspot B" union "hotspot C"


Tanks again!

Here is the example in action. I Need to mask the snow with multiple hotspots so i can cover all the windows.

thank you very much again! im going to use this last solution becouse it works faster (maybe becouse there's no need for krpano to disort a large png mask, but it does it with a vectorial plygon) and becouse the png mask had some errors (it was showing snow in incorrect areas when rotating the view, i dont know why).
unfailing questions:

Are you creating the hotspot with the editor plugin?

Can you think an idea to generate less, but "intelligent" snowflakes?, i mean, the 80% of the particles generated by the plugin are masked out, so they are overloading the pano without even been seen. if there was a way to "lead" or "direct" or "limit" the flakes to generate only in the hotspot area then it will snow much more intense with much less "flakes" therefor much less prossesing overload. I know it's a bit delirious but perhaps you think of something, i thought that may be creating a "flake.png" image with 4 or 5 flakes in it. so 1 flake-particle for the plugin will show 4 real flakes repeated, making less particles needed to give a feeling of intense snow.

Is there a way to limit the minimum distance between the closest flakes and the observer? because every a few seconds there is a flake (or a set of flakes) that passes way too close to the viewer therefore way too large in proportion to the others. it would be great to set a minimum range for the closest flakes (something like the "spreading" option that sets the maximum range for the farthest flakes, but the other way around)

Ok, that's all for today. i will still trying and learning about this great application
Thanks Umalo again for the particular classes you are really generous.
Bye
