yeah I had to think about that before, this is why I choose another option
I have tried to create rain with a rectangular and aplly sky shader and move it verticaly combine with dense fog, not bad for a cheap one though.
but then a weird occur when I look up, the rain is gone, of curse
then I tried to render it 2d aspek, yes rain is still in the sky when I look up but then it move horizontaly
using partikel obviusly not my choice
I really want to make a rain that has a raindrop splash in the ground
Is there anyone that have been succeded manipulated it cheaply?
please help me
