    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!

    If you transform the world on the Z axis a bit that will take care of the angle.

    Then create a solid for the bounce event. I had to rotate it on the Y axis to get the floor to look right.

    There might be a better way but that’s what I got.

    In the physics drop down, I would mess with adding wind in the X direction.

    That was my first thought too, but the bounce physics model doesn’t allow for wind which is pretty limiting.

    Yeah it seemed to me like Bounce was messing up wind. Guess I do need to work around.
    Thanks everyone!
