Programming snowfall

Recommended Posts

Hi there,

 

in a few weeks I'll be touring with a show around the Netherlands. I've got everything sorted out fine, but I'm stumbeling on a programming issue I can't solve.

The show contains 10 Martin 518, 4 MAC Kryptons and 4 250 washes. In one of the scenes there's supposed to be a snowfall. I want to do that with a gobo projection which "falls down from the sky".

The problem: a continuous snowfall would require the fixtures to go down and up again. Since snowflakes travelling upwards are kinda fake I'd like the fixtures to dim when they move upwards.

Ok: create a chase with on downwards movement, and one upwards... no problem; but when I'd want to do that with 18 fixtures, it'll certainly be a mess (since it's no option programming the same movement; that would suck)!

So how would you create such an effect. 100% on the way down, 0% on the way up; and all fixtures following a different pattern (that could be done by the offset of course). I'm stuck!

> 500 posts, time for a new T-shirt? ;)

Hi all,

I presume you are talking about running some breakup or dot pattern gobos down your backdrop or cyc to simulate the snow falling. To achieve a continuous effect will be pretty hard but if you were to write a chase with the first step using half the fixtures at the top of the backdrop or above at 100% brightness. Step 2 move these to the bottom of backdrop. Step 3 set these fixtures to 0% brightness and the other half of your fixtures to 100% brightness at the top or above the backdrop. Step 4 move these lamps to the bottom of the backdrop and the the 0% ones back to the top and just continue this cycle for a few steps possibably setting the attack modifier to "soft on / hard off". You will have to experiment with this for awhile to get close to the effect you are looking for.

Hi Ice,

probably an idea which is of help.

 

Try out a breakup gobo and project upwards onto a rotating mirror-tube.

a little haze on stage an it should be snow there. :wink:

 

 

cheers

P.S.:An more expansive way is to by a GAM FX with an "SnowFilm"
