Hey everyone...
Particular newb here looking for what I expect will be a simple answer to a question. I have created rain, and am mostly happy with it except that I need to change the angle of descent to about 45° so that it looks like it's raining sideways (sort of).
This is graphic rain, so it uses a Sprite as a particle. Physics model is Bounce (so it splashes at the end). Gravity is 300. Emitter velocity is 0. I'm very happy with what I have, except that I cannot figure the raining-at-an-angle part. I assume this is a simple matter, but when I mess around with what look like promising parameters it gets all messed up. Also, my particles are basically dashes and I would like their direction to match the angle of descent.
My workaround would be to precomp the whole thing, rotate it 45° and angle the floor layer to compensate for the rotation, but I am trying to learn Particular and I'd rather do it the right way rather than fake it.
Any and all help is greatly appreciated!

Rules of thumb

Ex. Groundspeed = 110 Kts x 5 = 550fpm rate of descent to maintain 3 degree ... This is not an Exact science as under FL180 you have to change to the local alt setting. ... To determine the wind correction angle you must know the crosswind ... The 45 degree multiplier is 0.7 for headwind, tailwind & crosswind components.

You should be able to rotate the world axis.

Never heard of them, but that doesn't mean I'm not. :P

Ex-NHL player. Not a name you run into as often as, say, Smith.

It's pretty rare!
I know NHL players are famous for getting their teeth knocked out, but I've never heard of one getting a letter knocked off of their surname!

I noticed the spelling was slightly off but figured it was a victim of Americanization at some point. I bet if you went back far enough you'd be related. Your great-great-great-great-great Uncle Pieter was a goatherd in Krakow or something.

My great-grandfather stowed away on a ship to get to The States, so that's not that far of a stretch...
