let it Snow (or rain).
Inspired by a tutorial of guitta bertaudi read a long hago i create falling Snow using cilindros that i apply the Snow flakesmaterial (materials collection special effects) todo that comes with vue. The top view shows how the cilindros are placed. I decreased the material scale todo get smaller snowflakes that are more dense as you can se in this screenshot.
Take care that you dont move the cilindros todo close todo the Camera todo avoid getting todo big flakes. You can se the material scale i used on the right and the small render shows the result.
Replace the Snow flakesmaterial with the rainmaterial and you get a nice rain. Select all cilindros in the Camera view and rotate them a bit todo let the rain fall either from top right todo bottom left or top left todo bottom right, of course if it snowing you want todo have some Snow on your plants todo.
There are several ways todo get Snow on plants. In this scene i used the fir that comes with vue.
In the material editor open the leaf material and change the overall color todo white. That what i did in this scene. You can a los duplicate your original plant, change the overall color of the duplicate todo white and rotate it slightly. That gives a mix of both. Or instead of rotating you can move the white plant slightly up to make it look as if Snow is on top of the branches. I hope that helps todo get started.
