Light expressions

Where the cart is going round the corner in the caves making sparks it produces a lot of light or flickering of light. Instead of keying the light intensity on and off manually, I wanted to have more of a random feel to the light intensity, to make it more natural.

I started to learn a little a bit about expression in maya and applied this to the lights intensity. After a while trying to make this work I kind of got a desired look and feel to the light, but the only problem was that this worked throughout the whole timeline, which I i didn't want. I still wanted to be able to have a master control over it turning on and off. This proved a little tricky as the new attribute didn't want to go under the right section on the light. Then though the hypergraph managed to put in under the section, (which was Lightshape1) and made this keyable.

Here's a couple of pic to show you what I mean.

In the video below you can see the effect of the expressions on the light.

This has worked really well to have a organic feel to this. Pleased with this :D ! !
